2.2.23 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
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/SS-I). 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
EB/SS-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,
