60 acre-feet, or two days detention at the average daily consumption rate. The

construction of this reservoir is estimated to cost about $130,000.

The Bureau of Reclamation originally planned to make diversions into Dove Creek

Canal during the April-October irrigation season. Now, however, it anticipates

cycling water through the canal during winter as the weather permits. Flow should

be allowed through the canal at least every two to three months if the proper

water rotation program is instituted. To assure an adequate water supply for a

treatment facility at Cahone, a 60-day non-flow period would be assumed, and the

corresponding storage volume requirement calculated. The anticipated cost of the

resulting 245 Ac-ft. reservoir is $300,000.

With 690 acre-feet of total storage capacity available in Monument Creek Reservoir

and a 100 acre-foot on-site storage pond, the Dove Creek treatment facility has

access to a sufficient raw water detention volume that operations will not be

affected when water is prevented from flowing in the Dove Creek Canal.

Supply Rates and Potable Water Storage:

As noted previously, the facilities being proposed to serve the Dolores Water

Conservancy District are adequately sized to handle the maximum demand expected

within a one-week period during their design life. It is the responsibility of

each individual service entity to provide the capacity within its system for

meeting fire flow requirements and peak demands over shorter time periods. Pre-

sumable, equalization of demand would be handled by the storage volume available

in the individual distribution networks. Evaluation of the distribution and

storage facilities of potential water customers is outside the scope of this study,

although existing system components are discussed in the following chapter. Values

for peak consumption and required fire flow, as well as minimum storage requirements,

should be determined by each particular service entity for its own system. This

assumes that the municipalitiea and service companies now operating and maintaining

distribution systems would retain that responsibility, and the DWCD would sell them

water treatment and transmission services.
