Feasibilitv Studies
Rod Bonnell, Secretary-Treasurer of the Grand Mesa Reservoir Company has completed the

Mesa Reservoirs #1 and #9.

The GMRC is a mutual ditch company and a non-profit corporation registered in the State of

shareholders that fail to pay their assessments, and the power to offer stock for sale to pay
back assessments.
Water Riahts
The GMRC holds storage rights in the following reservoirs:
Table 1: Reservoir Storage Rights, Grand Mesa Reservoir Company
Reservoir Name Stora e Ca acit acre-feet
Scales #1 203
Scales #3 129
Grand Mesa #1 559
Grand Mesa #6 172
Grand Mesa #8 379
Grand Mesa #9 153
Total 1,595 acre-feet
Records of the State Engineer's Office indicate that average annual diversions have been
approximately 1,000 acre-feet.
Proiect Alternatives
During the study of the Grand Mesa Reservoirs #1 and #9, the following alternatives were
evaluated:
1. The no action alternative.
2. Complete rehabilitation of the outlet systems for both reservoirs ($100,000)
3. Complete rehabilitation of the outlet systems for both reservoirs, as well as work to
address seepage and spillway problems on Reservoir #1 (Approximately $200,000)
The following is a summary of these alternatives:
No Action Alternative
This alternative was rejected because the storage restriction on Reservoir #1 would continue or
be increased, and because Reservoir #9 will be ordered breached by the State Engineer if the
outlet is not rehabilitated this year. This would mean the continued annual loss of 300 acre-feet
of storage in Reservoir #1, and the permanent loss of 153 acre-feet of storage in Reservoir #9.
