2,2.2.3 Environmental Baseline with Sandstone Reservoir Providing Supplemental

Irrigation and Municipal Water (EB/SS-M). The EB/SS-M run simulated operation of the

Little Snake River over the 1930-1982 period of record using the same demand schedule

prepared for the EB run with the addition of Sandstone Reservoir. Under Scenario

EB/SS-M, Sandstone Reservoir provided supplemental water to Wyoming irrigation rights,

and supplemental municipal water to Baggs and Dixon in the amount of 200 acre-feet

over the July-September period each year. Also, a minimum flow for fisheries of 24 c.f.s.

was provided below Sandstone Dam to the Savery Creek mouth.

Under EB/SS-M, Sandstone Reservoir storage water was used to meet the fishery

flow and to supplement only Wyoming irrigation demands, Irrigation demands on

reservoir water by Wyoming rights below the dam were limited to a total supply of 0.5

c.f,s. per 70 acres.

2.2.2.4 Environmental Baseline with Sandstone Providing Supplemental Irrigation and

Municipal Water. and Industrial Water (EB/S5-1). The EB/SS-I run used the same

demands as the EB/SS-M run with the addition of an annual release of 20,000 acre-feet

for industrial use at Baggs, provided at a constant rate year-round (27.6 c.f.s.). Under the

EBISS-I run, storage water provided supplemental irrigation water only to Wyoming rights

with demands on this water limited to a total supply of 0.5 c.f.s. per 70 acres, This

scenario with some modifications has been selected as the Water Development Baseline

for this study. The EB/SS-I run included the Two Bar Canal and Boone Lateral rights,
