April 22 1935

Fort Collins Colo.

Dear

Par

shall

I

received your curve of discharge for the eight

foot Parshall flume to be installed by the Twin Lakes Company at

'

4

'

the east portal of the

· win lakes tunnel. Many thanks.

I

undertsnad that work has not yet been commenced on the flume

0

In all probability the lining of the tunnel will not be completed

until about

~~y 15tho The amount

of

water that they will be able to

get thru this year will not be great and will not

go

far on 40000 acre

of lando

In

all my experience in the irkansas falley

I

have never seen

conditions

~

irrigations~and

prospects so discouraging as they are this Spring.

This is the second

eonsecutive

season that we have not been able to

K~

secure any storage water for the oldest reservoirso

W

e absolutely have

no irrigation storage.

I

have never befofe seen such bad dust stormso

fhese

dust storms remind me of descriptions

I

have read of sand storms

L

in

the

~ahara

desert and desertsfn Asia.

Our people feel very hopeful that the Oaddoa reservoir will be

~xi

built by a Santa Clauso

We

have also male application to the

P.W.A.

for an appropriation of $150000o

to be given the Reclamation service

for Trans-mountain surveys for water for the 1trijansas Valley and for

6ompensat1ng

Storage on the Western Slopeo lepresentatives have been

sent to Washington on both these propositions and have brought back

favorable reportso

W

e all wonder how long this dry spell will last

Regards to

you.

truly

L. T. BURGESS CHIEF HYDROGRAPHER SUBJECT:

I

am

forwarding today under

separate

cover blueprint of design

for a Parshall

flume at

the outlet

of Independence Pass

Tunnel, which has

been submitted by

Mr. Smith

for

our approval.

I

note that there has been a radical change in the design of the

floor from standard designs.

I

will appreciate the courtesy if you will

look over this drawing

and

see if it conforms in

all

particulars to your

own ideas, before approving the same. Please submit your views with

re-spect

to any

needed

changes.

2. In any event the company·shall not be liable for damages for mistakes or delays in the transmission or delivery, or for the non-delivery, of any message, whether caused by the negligence of its servants or otherwise, beyond the sum of five thousand dollars, at which amount each message is deemed to be valued, unless a greater value is stated in writing by the sender thereof at the time the message is tendered .for transmission, and unless the repeated-message rate is paid or agreed to be paid, and an additional charge equal to one-tenth of one percent of the amount by which such valuation shall exceed five thousand dollars. · .

Beyond these limits the company does not undertake to make delivery, but will, without liability, at the sen-der's request, as his agent and at his expense, endeavor to contract for him for such delivery at a reasonable price.

5. No responsibility attaches to this company concerning messages until the same are accepted at one of its transmitting offices; and if a message is sent to such office by one of the company's messengers, he acts for that purpose as the agent of the sender.
