Re: Cottonwood Hollow
Section 12, T7S, R8814
We have received additional information from Ray Walker concerning this
proposal and have discussed it with our Division Engineer, Orlyn Bell. Our
previous letter of February 27, 1984 questioned whether the reservoir could be
operated in conformance with the decree in Water Court Case 80CW359. Our
response to this additional information follows:
1. Mr. Walker indicates that 1.22 acre-feet per year would be required
to compensate for 13 units plus evaporation. The capacity of the
reservoir is currently estimated to be 1.28 acre-feet. The appli-
cants have agreed to develop a depth -area -capacity curve and install
a staff gage. It is our understanding that this will be required
prior to final county approval. We are in agreement with Mr.
Walker's calculation of the amount of water which will be necessary.
We will consider this issue to be resolved if the depth -area -capacity
curve indicates a total capacity in excess of 1.22 acre-feet.
2. Our Division Engineer has visited the site with Mr. Walker. He has
indicated to us that there was an inflow of sediment to this reser-
voir which may have had a sealing effect. At the time he visited the
site, outflow was approximately equal to inflow, indicating the
reservoir is not leaking excessively at the current time. The leak-
age from a reservoir is highly dependent upon ground water levels,
whether the ground is frozen, etc. As these factors change through
the seasons, leakage rates vary. For this reason, we ask that you
contact our Division Engineer to reconfirm that the reservoir is
holding water prior to final approval.
3. We understand that an incorporated homeowners association is the
intended institutional arrangement. Plat notes and covenants should
indicate that the homeowners association will be responsible for the

plan for augmentation and the reservoir. The plat notes and cove-
nants should limit each well to serving one dwelling, one horse, and
1,000 square feet of lawn and garden. Water rights involved in
80CW359 must be committed to serve this development.
We can recommend approval provided the above conditions are met and pro-
vided a leakage problem with the reservoir does not become apparent prior to
final approval. Please let us know if you have any questions.
Sincerely,
D. impson, P.E.
Assistant State Engineer
