the active storage pools over the 27-year study period for the Avery and
Sawmill Mountain Reservoirs.

Warner Point Alternative
Operation studies for the Warner Point alternative were similar to the
others. However, since Warner Point is on the mainstem of the White River,
no diversions were necessary from the North Fork and there was no need to
adjust for low flow patterns on the South Fork. The active storage pattern
for the Warner Point Reservoir is shown on Figure V-4.

The maintenance of the monthly minimum flow of 200 cfs from Warner Point to
Sheep Creek was possible 100 percent of the time. Below Sheep Creek,
monthly flows were less than 200 cfs ,!3 percent of the time. That situation
could be alleviated somewhat by altering the release pattern from the
reservoir. Warner Point Reservoir fill led in all but three of the 28 years
of study and had about 15,000 acre-feet remaining in active storage at the
1977 low, indicating additional releases could be made in very low flow
periods.

The hydropower potential for the Warner Point alternative was evaluated
using the results of the operation studies, but operation of the reservoir
for power production was incidental to the consumptive water uses of the
facility. Use of the full operating capacity of the reservoir would also
increase the hydropower yield. Optimization of the ultimate size and
operational criteria when considering project uses, minimum flows, and
hydropower, was beyond the scope of this study.

Pumping
The Sawmill Mountain Reservoir site is located at sufficient elevation to
serve the agricultural and coal areas by gravity. The only pumping required
for Sawmill Mountain is for oil shale demands in the Piceance Creek Basin.
For the Avery and Warner Point alternatives, pumping for agriculture and
coal is required in addition to the same oil shale pumping requirement. The
energy requirement for pumping varies each month, depending on the reserVOlr
level and the volume of water delivered. The average power consumption was
computed for each month as a part of the operation studies.
