Operation Studies Results

The primary purpose of the operation studies is to determine the storage
needs for each alternative plan and to compute the effect on White River
flows. Comparisons of monthly flows for conditions before and after the
projects were made for key locations along the Upper White River system.

1. North Fork of the White River below the diversion to Avery or Sawmill
Mountain Reservoir. - Althou9h the diversion locations are not exactly
the same for each alternative, there is no major inflow between the
two. Pre-project flows were assumed to be identical at each diversion
po i nt.

2. At the confluence of the North and South Forks of the White River for
the Avery and Sawmill Mountain Reservoirs. - For the Warner Point
alternative, the comparison point was selected just below the dam to
reflect the effect of the storage in, and the diversion from, the

reservoir.

3. At the Near-Meeker Gage. - This gage is about three miles upstream from
the town of Meeker.

4. At the Below-Meeker Gage. - This qage is located about 10 miles
downstream of Meeker.

Irrigation return flows from the project were estimated and assumed to
return to the river upstream of the near-Meeker gage. The municipal anc
domestic return flows were assumed to return to the river upstream of thE'
below-Meeker gage.

Water from the 70-cfs senior and conditional Stillwater right was assumed to
be diverted from the White River near its confluence with Sheep Creek. Thi~;
assumpt i on refl ects the resu 1 ts of ana lyses made of a Iternat i ve deli ver:f
routes to Piceance Creek from storage sites on the Upper White River. Those
analyses showed it would be more economica"1 to pump the water over the ridge
