To summarize, a functional Robbins Reservoir is essential to solving the District's current
problems and meeting future demand. It will allow capture of spring runoff in the Beaver
Creek drainage as well as storage of Mesa Creek water by exchange, thereby providing
a reliable, deliverable source of augmentation water, and allow the District to implement
its augmentation plans. It will provide the regulatory function needed to moderate
streamflow fluctuations for the benefit of downstream users during the winter.

The reconstruction and expansion of a multi-purpose Robbins Reservoir to provide for 75
acre feet of storage and the installation of the transfer pipeline between Mesa Creek and
Beaver Creek will provide the ability for the Districts to better utilize its water rights to
meet current and future needs. As shown by the yield analysis, the reservoir with 50 acre
feet of active storage capacity can provide a yield from 100 to 200 acre feet per year with
fills and releases. Without substantial additional cost, the reservoir provides for other
important water requirements needed throughout the year; such as for snow making, raw,,\
water storage for domestic use, irrigation water, drainage detention, etc. The reservoir \
also provides for an attractive and aesthetic benefit to the resort community. As shown
by the Project Cost Estimate, the cost for the reservoir and dam is approximately
$600,000 with approximately $100,000 required for the water transfer supply pipeline
between Mesa Creek and Beaver Creek. The utilization of the existing Robbins Reservoir
site with its natural setting for a reservoir and the important year around multi-uses
provided to the Powderhom Metropolitan District, results in an economical and feasible
proj ect.
