and Colorado River Pumping Facilities
' Dear Mr. Rosar:
INTRODUCTION
' Wright Water Engineers has prepared conceptual level cost estimates for the East Branch
Creek and Adobe Creek reservoir system facilities and for Colorado River pumping
facilities. The conceptual plan is to divert water from the Colorado River via the decreed
Mack Pumping Pipeline right near Fruita. The diversion point is approximately thirteen
miles downstream of the Gunnison-Colorado River confluence. A project location map,
Figure 1, (at report back) shows the location of the reservoir system and pumping facilities.
The diverted water would be pumped to either one or both reservoirs which are located
above the Government Highline Canal (GHC) and the Grand Valley Canal (GVC) or
directly to the canals. The Government Highline and the Grand Valley Canals have senior
water rights on the Colorado River. Downstream from these canal diversions is a critical
15-mile reach of river where the streamflow is sometimes insufficient for endangered fish
species. By providing water from the reservoirs to the canals by exchange, the streamflow
of the Colorado River would be increased in the 15-mile reach, thereby providing improved
habitat for the endangered species.
Several alternatives to this conceptual plan are also analyzed. These alternatives include
pumping from the Colorado River directly to the Highline and Grand Valley Canals from
alternate points of diversion.
