The biological opinion for Taylor Draw Reservoir identified
depletions of 560 acre-feet in April, 1320 acre-feet in May,
1520 acre-feet, and 600 acre-feet in July for a total annual
depletion of 4000 acre-feet. These depletions were assumed to
occur in all years, except dry years where a monthly depletion of
1800 acre-feet was assumed to occur. Total depletions in dry
years was assumed to be 12,600 acre-feet. These depletions, along
with evaporation loss, were modeled to occur from Taylor
Reservoir.
Test trials using the Reservoir parameters listed in the table,
and the assumed depletions produced a relatively stable Reservoir
with sustained yields as described in the biological assessment.
