Comanche Station Power Plant - Water Rights Investigation
Public Service Co. (PSC) annually requires approximately 7,900 acre-feet of water from the Arkansas River to satisfy the industrial water demands for existing and future power generation at the Comanche Station power plant near Pueblo. In order to provide efficient and flexible use of its available water supplies, PSC engaged Wheeler to perform an engineering analysis to support a plan of exchange to reuse and successively use portions of its raw water supply that derive from fully consumable sources.
The Comanche Station Power Plant is located southeast of the City of Pueblo and diverts its water supply from the Arkansas River via the Comanche Station Pumping Plant. Water that is not consumed at the Power Plant is discharged into the St. Charles River approximately six miles upstream from its confluence with the Arkansas River. When flow conditions on the Arkansas River permit, reusable discharge is diverted, by exchange, at the upstream location of the Comanche Station Pumping Plant and/or is stored in Pueblo Reservoir.
The streamf low regime and "exchange potential" within the reach of the river between the mouth of the St. Charles and Pueblo Reservoir was evaluated using a computer model of the Arkansas River originally developed by Wheeler. The computer model was developed using historic daily streamflow data and diversion records for the ditch structures in this reach for the period 1976 to 1981. For PSC's exchange plan, the amount of water that could be diverted by exchange at the Comanche Station Pumping Plant or at Pueblo Reservoir would be governed by the calculated exchange potential, reduced by the amount of water being diverted pursuant to senior, conditional exchange decrees, effective in this river reach. As part of the engineering analysis water quality data for the effluent discharged from the Comanche Station Power Plant was reviewed.
Ski Monarch,
LLC
- Municipal and Recreational Water Use Assessment
Ski Monarch, LLC (Monarch) provides water and sewer services to the Monarch Ski Area, the Town of Garfield, and the Heart of the Rockies Campground, all located near the Town of Salida in Chaffee County. Monarch obtains the municipal water supply for its service area from waters tributary to the South Arkansas River.
Wheeler provides engineering services for Monarch to evaluate and assess its current and projected water demands, population trends, and per capita water use. In order to assure that adequate water supplies are available to satisfy Monarch's future water demands within its service area, Monarch filed applications to the Division 2 Water Court seeking conditional water rights (December 1996) including new points of diversion and storage, and a river exchange on the South Arkansas River. As Project Engineer, Wheeler was responsible for estimating storage and diversion requirements for Monarch's water rights application. The assessment of Monarch's water supply and storage requirements included consideration of future artificial snowmaking operations at the Ski Area, future increase of domestic water demands within its service area due to projected population increases and development plans, and storage.

behalf of Monarch, Wheeler has also participated in discussions with the United States Forest Service concerning protection and preservation of Monarch's water rights and the Forest Service's minimum streamflow water right claims.
Fountain Creek Basin
Since the early 1970's, W.W. Wheeler and Associates, Inc. has provided (and continues to provide) engineering services to numerous clients within the Fountain Creek basin. These clients include the following: 1) Stratmoor Hills Water and Sanitation District; 2) Security Water and Sanitation District; 3) Widefield Homes; and 4) the City of Fountain.
In order to produce a dependable municipal water supply for its clients along Fountain Creek, Wheeler has provided engineering services to help develop plans of augmentation. As part of the development of the augmentation plans, Wheeler provided complete engineering services which included water use and needs, projections of water demands, evaluation of water rights yields, and assistance in permitting and regulatory requirements for diversion and storage facilities. To analyze the exchange potential along the mainstem of Fountain Creek, Wheeler developed a daily surface streamflow model.
Entities which withdraw groundwater from the Widefield Aquifer (an off-channel alluvial aquifer located near Security and Widefield) entered into an agreement in which pumping from the aquifer is monitored and controlled. The Widefield Aquifer Stipulation was agreed upon in 1975 for the purposes of settling water rights disputes among various water users, maintaining reasonable water levels, and providing reliable supplies for municipal uses. Wheeler was instrumental in the development of the Stipulation. The U.S. Geological Survey MODFLOW groundwater model was used by Wheeler to analyze the affects of well pumping on the water levels in the Widefield Aquifer.
Colorado Water Protective and Development Association
The Colorado Water Protective and Development Association (CWPDA) was founded in 1964 by Arkansas Valley farmers to protect members against legislation that could curtail irrigation well diversions. The current membership of CWPDA is over 800 wells, which pump over 50,000 acre-feet. The purpose of CWPDA is to protect and develop the underground and surface waters of the Arkansas River Basin. Since its inception, a primary focus of CWPDA has been to annually obtain replacement water to cover depletions from member wells.
Since 1994, Wheeler has been responsible for providing water rights and hydrologic engineering to CWPDA. The primary focus of the engineering has been assisting CWPDA to comply with the Rules and Regulations governing groundwater withdrawals within the Arkansas River basin. Engineering services have included the development of a computer model and databases which enable CWPDA to comply with the governing Rules and Regulations. Wheeler has performed hydrologic studies to determine stream depletions resulting from well pumping and stream accretions resulting from return flows of transmountain water and lawn irrigation using computer models developed by Wheeler. Wheeler has assisted CWPDA in the acquisition of replacement water which has included the evaluation of numerous water rights to assess their value with respect to meeting CWPDA's replacement needs. Wheeler has been involved in the administration of CWPDA's substitute water supply plans which has included interfacing with CWPDA and State agencies for purposes of developing procedures to ensure compliance with the governing Rules and Regulations.

SIMILAR PROJECTS
City of Thornton - Agricultural Water Rights Transfer
In order to provide future raw water supplies, the City of Thornton acquired over 20,000 acres of land and the associated water rights in the Cache la Poudre River basin near Ft. Collins, Colorado. Historically, these water rights in the Water Supply and Storage Company (WSSC) were used for agricultural irrigation of about 17,500 acres. The City made application to the District Water Court, seeking to change the use of the water rights from agricultural use to municipal uses. Absent protective terms and conditions in the change of use proceeding, the transfer of water rights could have resulted in significant impacts on the remaining water resources and water rights of the Cache la Poudre basin. The Northern Colorado Water Conservancy District (NCWCD) objected to the proposed change of use and retained Wheeler to provide engineering analysis of the surface water portion of the proposed change.
The major focus of the Wheeler investigations was a determination of the amount of water that was historically "consumptively used" through exercise of Thornton's water rights in the WSSC, including direct flow rights, storage rights and waters imported from the Colorado's Western Slope. Wheeler provided a full range of water resources engineering services for this litigated water rights transfer case, including hydrologic investigations related to water supply sources, agricultural engineering related to potential evapotranspiration, field investigations to determine canal seepage losses and on-farm irrigation efficiencies and expert witness testimony in the District Water Court.
Kiowa Resources - South Platte River Exchange Project
The Kiowa South Platte River Exchange Project was developed to provide a new source of municipal water supply to the Denver metropolitan area. Key components of the project include senior agricultural water rights, facilities for diversion, storage and pumping, and a water rights exchange on the South Platte River. Under operation of the Project, water which historically was diverted for irrigation in areas north of the Denver metro area (downstream of the discharge from the Denver Metro Wastewater Treatment Plant) would be diverted, by exchange, at a new upstream location near Chatfield Reservoir in the south-central metro area. Potential yield of the Project is approximately 4,000 to 5,000 acre-feet per year.
Wheeler developed a computer model of the South Platte River to evaluate the streamflow regime within the river exchange reach and to determine the exchange potential. The computer model was developed using historic daily flow data from USGS stream gages and diversion records for the major diversion structures in the exchange reach for the period 1950 to 1990. For the Kiowa plan,

•
the amount of water that could be diverted by exchange at the upstream locations would be limited by the exchange potential less any diversions made pursuant to senior exchanges determined by decree and/or stipulation.
As part of the engineering analysis for the Kiowa Exchange Project, optimum storage requirements and reservoir capacities were determined based on a range of project yields. Wheeler also investigated the permitting and regulatory requirements associated with the location, design, and construction of the diversion, pumping and storage facilities.
Colorado River Decision Support System
(CRDSS)
The Colorado River Decision Support System is a system of models, databases and utility programs that is used to facilitate informed decision making for issues related to management of the water resources of the Colorado River basin. The CRDSS is centered around databases containing historical information on streamf low, climate, and water uses, as well as tabulations of water rights. This computer-based system allows decision makers to simulate potential development alternatives and planning policies and to evaluate possible consequences related to water resource issues including new water projects, water exchanges and transfers, instream flow appropriations and administration policies pursuant to the Colorado River Compact.
Wheeler was a member of the consulting team selected to design and implement the CRDSS, in particular the development of the Water Resources Planning Model (WRPM). The State of Colorado's Stream Simulation Model (StateMod), an adaptation of the BESTSM model developed by Boyle Engineering Corporation was adopted as the WRPM. StateMod is a network allocation model in which major stream features such as gaging stations, reservoirs, diversion structures, etc. are represented as nodes in the network. A separate WRPM was developed for each of the five principal drainage basins on Colorado's western slope (Yampa, White, Gunnison, San Juan/San Miguel and Colorado main stem). Wheeler was responsible for the analysis of the direct flow, storage, and instream flow water rights that were included in the prototype WRPM.
Through interviews with the respective Division Engineers and water users, Wheeler was also responsible for the development of operational rules for the major reservoir operations (including the Federal storage/irrigation projects). Wheeler was responsible for investigations related to the "consumptive losses" in the Colorado River basin, including recommendations for appropriate changes to the USBR's methods for estimating evapotranspiration (ET) by irrigated crops.
Vancil Reservoir and Recharge Project
The Vancil Reservoir and Recharge Project was developed to create a new surface storage facility and to utilize storage in the alluvial aquifer of the South Platte River to regulate seasonal fluctuations of the South Platte River streamflow. The fundamental concept of the Vancil Project is to divert high rates of flow (up to 1,000 cfs) from the South Platte River during periods of surplus flow, using the existing diversion facilities of the Riverside Irrigation District. The water is delivered to a downstream, off-channel reservoir (Vancil), where it can be released during the late summer months to provide supplemental irrigation supplies at the lower end of the Riverside system. Significant canal seepage losses occur during these diversions, recharging the alluvial aquifer of the South Platte River. The accretions to the river attributable to these seepage losses (recharge) are delayed in time. These recharge "credits" are then available to augment the flow of the river. The recharge credits can also be used to offset or replace the depletions caused by the pumping of groundwater
•
•
from irrigation wells completed in the alluvial aquifer, as well as provide supplemental water supplies for other uses in the river basin.
Wheeler developed procedures to estimate the amount of seepage loss (recharge) from the various reaches of the Riverside Canal and from Vancil Reservoir, and modeled the timing of the recharge accretions back to the South Platte River. Wheeler prepared accounting forms to monitor the operation of the recharge plan and assisted in the adjudication of the water rights for the recharge project in the District Water Court. Wheeler also prepared engineering design plans and technical specifications for the construction of Vancil Reservoir, a 7,000 acre-foot storage facility located near the Town of Snyder.
Climax Mine - Readjudication and Consolidation of Water Rights
The Climax Mine and Mill is located in central Colorado at the summit of Fremont Pass, near Leadville. The Climax Molybdenum Company has operated the mine for over 70 years. The mine has historically been one of the largest mines in the world, and has diverted and used approximately 34,000 acre-feet of water for mining and milling operations. Thirty separate water rights and transfers have been adjudicated for use at the mine to support the water supply. Industrial activities have significantly changed the geography and configuration of the water supply systems as the mine was developed. As a result, changes have been made in the operation of the water system and several decreed diversion points under the Climax water rights are no longer useable. Because of these changes Climax management found it necessary and prudent to readjudicate their portfolio of water rights in an effort to consolidate and simplify the administration and management of water, and to update the decreed locations and use to conform with present practices.
Wheeler has performed a detailed analysis of historic water and expected future use at the mine and mill for the purpose of supporting the Climax application for readjudication of the water rights. The portfolio of water rights that were analyzed include both tributary, transmountain, and developed mine water rights; and the mine facilities span three different basins because of its location at the Continental Divide. A detailed computer stream flow model was also constructed to determine the long term water balance (and depletions) based on actual flow records.
Arapaho National Wildlife Refuge - Water Use Assessment
Study
The Arapaho National Wildlife Refuge (ANWR) is located adjacent to the Illinois River, a tributary of the North Platte River near the Town of Walden, Colorado. Beginning in 1967, lands within the ANWR have been acquired by the U.S. Fish & Wildlife Service (USFWS) for purposes of providing nesting, feeding and resting areas for migratory waterfowl, as well as to preserve habitat for other wildlife species. Currently, in excess of 18,000 acres of land are situated within the refuge, with over 10,000 acres receiving water via surface diversions from the Illinois River, Potter Creek and a number of smaller tributaries. Prior to acquisition of the lands for the refuge, the lands were irrigated for hay production and pasture as a part of several cattle ranch operations.
Wheeler was retained to evaluate stream depletions and other possible water resources impacts associated with the existing and proposed operations of the refuge. In this regard, Wheeler performed investigations to quantify the historical consumptive uses pertinent to agricultural irrigations and the current consumptive use and stream depletions attributable to the refuge operations. The primary focus of the project was a determination of the change in the magnitude of water use, and corresponding stream depletions, that has occurred as a result of the change from agricultural irrigation use to a combined use of irrigation and wildlife habitat enhancement.

REPRESENTATIVE PROJECTS WITHIN THE ARKANSAS RIVER BASIN
Arkansas River Basin Study
Boyle Engineering provided engineering/technical services for the state of Colorado to support the defense of a lawsuit filed by the state of Kansas. The lawsuit concerned alleged violations of an interstate compact that governs administration of the waters of the Arkansas River.
The Arkansas River basin covers a drainage area of about 25,000 square miles; the river originates on the eastern slope of the Rocky Mountains at elevations in excess of 14,000 feet. It emerges from deep, rugged canyons at Pueblo, Colorado, and begins its long, gradual traverse of the plains of eastern Colorado and western Kansas. An important agricultural economy that is heavily dependent on the river for irrigation water supplies has developed in this region since the mid-1800's.
Boyle provided technical services to the state for its analysis of conditions within the basin, with primary emphasis on surface and ground water hydrology. Boyle had direct responsibility for data collection and analysis in the areas of soils, hydrology, climatology, geology, land use, wells, water rights, diversions and conservation measures. Boyle also made an in-depth investigation of the complex legal and institutional arrangements governing the manner in which the waters of the basin are appropriated and allocated.
Great Plains Reservoir Hydrology Study
The Great Plains Reservoirs System is comprised of four interconnected reservoirs in southeastern Colorado. The reservoirs are filled by diversions from the Arkansas River and supply irrigation water for agriculture in the region.
In 1992, the State of Colorado decided to establish a new state park in southeastern Colorado. The state asked Boyle to help identify potential water supplies for wildlife and recreation in the park while maintaining the viability of irrigated agriculture in the Lower Arkansas Valley.
Boyle conducted the analysis by using a reservoir operations model to estimate evaporation, releases, water level requirements, and water quality for all of the reservoirs. Boyle engineers identified over 15 water supply combinations available to the Great Plains Reservoirs, then analyzed the alternatives for yield, costs, and potential fatal flaws. After selecting five reservoir configuration alternatives, the water supply required by each reservoir was identified, along with the reservoir's ability to provide recreation, wildlife, and agricultural benefits. In addition, mitigation strategies were developed to offset the potential impacts of each alternative on irrigated agricultural and other water users. Boyle also performed a regional economic analysis to determine how water transfers from irrigated agriculture may impact the local economy.
Fort Lyon VA Medical Center Well Replacement
The VA Medical Center is located in the Arkansas Valley of southeastern Colorado. It was constructed shortly after the turn of the century. The Medical Center operates two separate water systems. Raw water for potable supplies is obtained from five wells drilled into bedrock aquifers
WHEELER / BOYLE QUALIFICATIONS
•
•
at depths of between 100 and 300 feet. Water from these wells is treated by reverse osmosis before use in the potable system. The Medical Center also operates seven shallow wells, all completed in shallow alluvial deposits adjacent to the Arkansas River. These wells supply water for irrigation and fire protection.
Boyle Engineering Corporation was retained by the Department of Veterans Affairs to design and construct additional wells to supplement the existing bedrock wells.
The first element of the project consisted of an inventory of existing wells, including construction details, water levels, and pumping history. Well logs were compiled in order to prepare an interpretation of the site's hydrogeology, and as a basis for design of supplemental wells. Well designs were then prepared to closely match the anticipated subsurface conditions. Designs were also prepared for the permanent pump, well head facilities, well-house and well-house piping, and transmission main to the facility. Because of the remote location of the well, an instrumentation and control package was incorporated in the final designs which will allow for remote operation and monitoring of the well using a telemetry system.
Reverse Osmosis Water Treatment Plant
Located in the Arkansas Valley, the City of Las Animas has a history of municipal water with high total dissolved solids (TDS) in the range of 3,500 mg/L. As a result, the residents use bottled water extensively, and have experienced substantial costs in home water softeners, laundry expenses, and water heater replacement. Boyle Engineering and Gilbert B. Morrill, P.E., were retained to establish the technical feasibility of a reverse osmosis (RO) treatment process, then prepare final design and construction documents for a water treatment facility that would provide 1.0 MGD of treated water from a ground water supply with high TDS.
The first phase of the project involved the installation of a 3-gallon-per-minute pilot plant. The purpose of the pilot study was to determine the technical feasibility of the RO process and evaluate the membrane fouling characteristics of the water. Following approval of the pilot plant report, engineers prepared plans and specifications for the facility that would involve the following treatment process: pretreatment for pH adjustment and anti-scaling, membrane filtration, post-treatment degassifier, corrosion control, fluoridation, and chlorination. The facility, located adjacent to the existing 2 MGD water storage reservoir and pumping station, would achieve a treated water quality with TDS not exceeding•750 milligrams per liter based on a 30 day average. Treated water from the plant will then be pumped directly to the existing storage reservoir. The process area is housed in a new 5,300-square-foot prefabricated metal building which includes an office/laboratory, electrical room, chemical feed rooms, and a restroom.
Services also included bidding and construction phase support, modifications to seven existing wells, site improvements, an operation and maintenance manual, start-up assistance, and operator training.

Boyle Engineering Corporation provided engineering and technical services to the city of Greeley, Colorado, to investigate the yield of existing water rights and water supply facilities under severe
•
•
drought conditions. During the study engineers investigated selected alternatives for overcoming potential water supply deficiencies during severe drought under present and future demands. The city of Greeley draws its water supply from three main sources - the Cache la Poudre River, the Big Thompson River, and the Colorado River through the Colorado-Big Thompson and Windy Gap Projects. To evaluate the behavior of potential yields from all sources available to the city under severe drought conditions, engineers performed a joint stochastic analysis of the three basins and developed a model of these supply sources. The stochastic analysis generated 50,000 years of streamf low data for each basin, from which drought sequences representing 20-, 50-, and 100-year droughts were selected. Engineers developed a MODSIM model of the basins to evaluate the potential yield available to the city during the selected drought sequences.
The second phase of the study addressed the operational aspects of the system to quantify the portion of the potential yield that can be used during the drought sequences. Engineers identified any deficiencies in supply under present and future demands and tested alternatives for overcoming those deficiencies.
Colorado River Decision Support System
The Colorado Decision Support System (CRDSS) is a collection of computerized databases and models designed to help Colorado agencies make informed decisions and Colorado River issues. CRDSS currently includes four major components: 1) tabular databases on historical river flows, diversions, and climate and agriculture; 2) mapped databases on topography, irrigated lands, streams, diversion structures, reservoirs, cities, counties, and water districts; 3) a consumptive use model; and 4) five water resources planning models for simulating monthly flows, diversions, and reservoir operations in the five major sub-basins of the Colorado River within the state.
Boyle Engineering was engaged by the Colorado Water Conservation Board to enhance the water resources planning models beyond their current level of detail, and to support the development of an additional system component—the water rights administration tool. The water resources planning model upgrade involves incorporating approximately 25 percent of each basins water use, which was left "in the gage" in the first versions of the models. Because this use is typically spread among numerous small diversions and reservoirs, the enhancement is accomplished by subdividing each basin into several dozen smaller drainages, and aggregating operations into a single diversion for each subdivision. Parameters characterizing each aggregated diversion, such as diversion capacities and water rights, must be developed from the parameters for the individual structures represented in the aggregation. The models will be recalibrated, providing an opportunity to refine aspects of the early models based on new data. or more detailed analysis than was possible in the first phase of model development.
The water rights administration tool is a collection of spreadsheets detailing daily operations on the river. It includes curtailment analysis, which will permit river administrators to test the effects of curtailing junior diversions to satisfy senior rights, before actually putting the call into effect. Boyle§ role in this project will be to gather operational information from water commissioners, develop spreadsheets, and specify functionality of the curtailment analysis.

is located on Muddy Creek, a tributary of the Colorado River, approximately five miles north of Kremmling, Colorado.
The zoned embankment dam, designed by Boyle for the Colorado River Water Conservation District, is 120 feet high with a 1,900-foot-long crest. The dam has two spillways to convey flood waters safely past the dam. The service spillway, a conventional ogee crest and concrete lined channel, is designed to pass the 100-year flood. An adjacent emergency spillway, together with the service spillway, will pass larger floods up to the probable maximum flood.
The emergency spillway was originally designed with a labyrinth weir crest and an unlined downstream channel excavated in rock. A 1/45th scale model of the spillways for Ritschard Dam was tested at the U.S. Bureau of Reclamation§ Hydraulic Research Laboratory in Denver to confirm the hydraulic performance of both the labyrinth weir emergency spillway and ogee crest service spillway. However, a site-specific probable maximum precipitation study revealed a lower probable maximum flood. With construction at 85 percent complete, Boyle redesigned the labyrinth spillway as a three-stage fuseplug and a raised ogee crest which will provide 6,000 acre-feet of additional storage in the reservoir.
The outlet works intake structure is a 120-foot-high tower with four gates at different elevations to allow selective withdrawal of reservoir water. The ability to select the quality of reservoir water released will enhance the water quality of the tailwater fishery below the dam.
Denver Water System Model
Boyle Engineering was selected by Denver Water to evaluate Denver's extensive raw water rights and supplies in the Colorado and South Platte River Basins and to develop a comprehensive computer model for analyzing and managing its raw water supply system.
Denver's water supply is derived from many sources on both sides of the Continental Divide. On the West Slope of the Rocky Mountains, water is diverted from three separate basins tributary to the Colorado River and conveyed through the mountains to Denver. On the East Slope, Denver has extensive water rights for direct diversion and storage on the South Platte River. To accurately represent system operations under Colorado's system of prior appropriations, the operations of all other significant water users on both sides of the divide must be included in the model. These users include the massive Colorado-Big Thompson and Fryingpan-Arkansas Project, the cities of Colorado Springs and Aurora, and many other municipal and agricultural users.
In total, the.model represents the Colorado River and its operations from the headwaters to virtually the stateline (8100 sq. miles) and the South Platte River Basin from the headwaters to just downstream of Denver (4700 sq. miles). The model includes 20 major reservoirs, six significant transmountain diversion facilities, over 200 key waters rights, numerous complex exchange and augmentation arrangements, and the ability to simulate conjunctive surface and ground water operations. A daily time step was used in the simulation over the entire 50-year study period. The Boyle Engineering STream Simulation Model (BESTSM) was used to model the system.
The model provides Denver Water with a flexible tool to analyze alternative management and operational scenarios. Through these analyses, options for better use of existing supplies and potential new supplies can be easily evaluated. In particular, mutually beneficial arrangements through integrated operations of supply systems owned by Denver and other water purveyors can be developed and
tested
to achieve win-win solutions to water supply problems facing the Front Range of Colorado.S

BESTSM HYDROLOGIC MODELING
The planning and design of water resource supply projects requires thorough accounting of the amount and timing of streamflows in a river basin. Water resource managers often use simulation models to make these determinations. Boyle Engineering has developed a general purpose streamflow allocation model, Boyle Engineering STream Simulation Model (BESTSM), to simulate the operations of simple or complex stream networks under specified priority criteria, such as a prior appropriations water rights system.
Hardware/Software Requirements
BESTSM is written in FORTRAN 77 and is designed to run on an IBM-compatible PC with at least a 386 processor, approximately 4 MB of RAM, and 20 MB of harddisk space. The actual amount of RAM and hard disk space required depends on the size of the system being simulated and whether daily or monthly simulation is desired. The model has a relatively fast execution time. For example, a model run simulating the operations of the City of San Diego's ten reservoir system takes approximately two minutes for a 103-year study period using a monthly time step on a 486 25mhz machine.
BESTSM Development
BESTSM was originally developed for analysis of water availability in the Rio Ruidoso Basin in New Mexico, but was designed for application to any river basin by changing input data sets. The model incorporates several valuable features, such as the option of daily or monthly simulation timesteps, calculation of virgin flows, the ability to easily handle complex cross-linkages in parallel branches of a stream network, and the ability to easily simulate transfers and exchanges. Subsequent applications of various forms of the model have included the San Miguel, Upper Colorado, Upper South Platte, and Arkansas River Basins in Colorado; Shell Creek in Wyoming; the Rio Grande in New Mexico and Texas; and the Platte River in Nebraska. A current application of the model is the simulation of the raw water supply system for the City of San Diego. San Diego's complex system consists of ten reservoirs in four river basins, two major aqueducts, and one ground water basin. BESTSM is also being used to model portions of the South Platte and Colorado River System for Denver Water.

In BESTSM, a river basin is represented as a system of "linked nodes." Each node or measurement point represents a diversion, a stream gage, a reservoir, a point requiring a minimum in-stream flow, or any other location where information is known or needed. The nodes in the system are "linked" by river channels, canals, pipelines, or aqueducts. BESTSM performs all basin accounting and flow routing between the river nodes. The model can easily represent complex networks consisting of multiple stream branches with complex cross linkages and off-channel facilities. A figure demonstrating the use of a linked node system is included at the end of this section.
The simulation function of BESTSM is primarily controlled by the water rights input to the model. Using water .allocation priorities, the model will simulate the following types of water rights:
•
•
• • • •Direct flow rights Reservoir storage rights In-stream flow rights
Operational rights (rights pertaining to reservoir releases)
Each water right is given a basin priority and location by the user. BESTSM then sorts the water rights by input rank and simulates the water rights in order of priority.
BESTSM allocates water to a diversion or reservoir based upon available flow, water rights, diversion or storage capacity, and demand. The water' allocation scheme used in BESTSM is a direct solution method. The basic steps in the BESTSM direct solution process are:
1. Determine available flow at each node at start of period. 2. Determine the most senior right in the basin.
3. Determine flow available for diversion by this water right through a check of all downstream nodes.
4. Limit diversion by water right, headgate capacity, carrier canal capacity, available flow, or demand.
5. Simulate diversion and adjust river flows at that node and all downstream nodes. 6. Find the next senior right and repeat the above allocation process.
For simulations using a daily timestep, flows must be routed between nodes. A linear routing procedure is used and has proven effective in duplicating the behavior of river systems. The use of a linear routing procedure facilitates the daily simulation of water allocation, as the principle of linear superposition can be invoked for simulation of water rights, return flows, reservoir releases, or other flows. Equally as important is the ability to implement an efficient, direct solution for determination of flow available for diversion. If a non-linear routing function was used, the water allocation procedure would become very cumbersome and would require a time consuming trial and error procedure.
Simulation of Reservoir Operation
BESTSM can simulate complex reservoir operations as well as the allocation of streamflow. Any number of reservoirs can be simulated within the basin node network. Reservoirs can be located on a main channel or off-channel. For each reservoir, multiple pools or accounts with multiple owners in each type of account can be operated. Examples of different pools or accounts include flood pool, recreation pool, storage for irrigation, and storage for municipal water supply. The storage for irrigation pool could be further subdivided into water stored this year, water stored last year, transmountain water, water exchanged from another reservoir, and other categories. Within each of these categories, there could be multiple ownership accounts for different ditch companies or individual irrigators.
Reservoir storage simulation is based on reservoir rights and specified operating rules. Releases can be made to satisfy .unmet demands at downstream diversion, produce hydropower, or maintain minimum instream flow requirements. BESTSM can release water from an on-channel reservoir, an off-channel reservoir, or a combination of releases from several reservoirs to meet demands.

BESTSM can also handle the release of water from a downstream reservoir for diversion upstream by exchange or release from one reservoir for storage in a second reservoir. A reservoir balance is computed using reservoir inflow, releases, spills, bypasses, evaporation, precipitation, and seepage. Evaporation and seepage charges are pro-rated to the reservoir owner's accounts..
For the calculation of potential hydropower production, BESTSM is able to simulate the amount of flow and the head. Combining these variable elements with appropriate constants defined by the type and efficiency of the turbine, alternative powerplant configurations and system operations can be evaluated.
Many reservoir operations can be easily handled using existing routines, but the modular structure of BESTSM allows for the input of special subroutines to handle specific operations unique to a particular basin. For example, this option was used to simulate the complex operations of the Pueblo Reservoir Winter Water Storage Program in the Arkansas River Basin in Colorado.
Presentation of Results
In addition to easily representing and simulating complex river basins, BESTSM has excellent capabilities in presenting the results. In large, complex basins, particularly when a daily time step is used, the volume of output can be overwhelming. BESTSM's efficient report writer feature allows the user to select the information desired, at the locations desired, for the period desired, and in the form desired--all as a post-processing function. This is accomplished by having all of the model output stored in a binary file. The report writer can then enter this file, extract the needed information desired, and present it in the appropriate manner. This feature allows for the efficient management of information for analysis, and eliminates the need to re-run the model when the required option is not known in advance. The report writer also eliminates the need for large, unnecessary print-outs and the consequent storage problems.
BESTSM's report-writing function includes both graphical and tabular output formats. Graphic representation of model output is accessible from BESTSM's main menus and available in several formats, both two-dimensional and three-dimensional. BESTSM's graphic capabilities will support a range of printing and plotting devices for the production of graphs.
Model Documentation
A comprehensive documentation and users manual has been developed for the BESTSM model which details the theory of the model, outlines the input data files, and provides input data files for an example river basin problem. In addition, a flow chart of the model and all model variables are documented in the manual.
