III. REPaID' ON OPERATIONS OORING WATER )!EAR 1982

A. Ruedi Reservoir

I
The 1981 water year ended on Septanber i30, 1981, with Ruedi Reservoi3
containing 98,490 acre-feet of water while making a release of377 ft Is.
This release rate was increased in mid...,October to about 150 ft /s and
continued until mid-June when the release was again increased to slow
the rate of storage. On June 30 the reservoir was filled to near the
top of the active storage capacity, anq thereafter the release rate was
adjusted to match inflow and outflow. IThe reservoir maintained a rela-
tively constant elevation throughout !:lle remainder of the water year.
~ inflow declined' fran about 600 ft3;fs on July 1 to approlC:i.nlately 160
ft /s on Septanber 30, 1982. '

.

During water year 1982, no temporary water sales contracts for Ruedi
water were initiated, nor were any reqq.ests made for releases of stored
water by the four long tenn storage contract entities. With no de:nands
on the stored water Ruedi Reservoir ended water year 1982 with alrrost
2,000 acre-feet IlOre water in storage 1ihan when the water year began.
The content on September 30, 1982, was 1100,480 acre-feet.
