H. Project Water Sales and Deliveries;

The project made available 125,000 acre-feet of water to the
District during water year 1983. From October 1 throu9h April 30, 340 acre-
feet of 1982 allocated water was delivered, From May 1 through the end of
September, 810 acre-feet of the 1983 allocation had been delivered. Of the
1,150 acre-feet of project releases, 28; acre-feet were Municipal and
Industrial use. The project water re1easeo from Pueblo Reservoir is shown
on exhibit 17.

project's five reservoirs.

J. Flood Control Benefits

,
During water year 1983, there waJ one occurrence in which Pueblo
Dam was used to control flow in the Arkansas River and one occurrence in
which Ruedi Dam was used to control flow in!the Fryingpan River.

The flood control at Pueblo Dam began on June 16 when the State of Coloado's
Division of Water Resources office requested the project reduce the release
to control the flow on the Arkansas River at Avondale. The stored water was
released beginning on July 1. The U.S. !Corps of Engineers estimate the
flood control benefits to be $47,000, as ~ result of this reservoir opera-
tion.

.

The flood control at Ruedi Dam began in early June when the outflow from the
reservoir was controlled by storing water in the reservoir and by diverting
water from the Fryingpan River Basin to the Arkansas River Basin. Without
regulation at Ruedi Dam and diversion capabilities into the Arkansas River,
flows in the Fryingpan River below Ruedij Dam would have been more than
doubled until the middle of July. The U.S~ Corps of Engineers estimate the
flood control benefits to be $80,000, as a I esult of these operations.

Table g shows the flood control benefits neceived on both Ruedi and Pueblo
Dams '
