<br />At the end of September 1972 Blue Mesa
<br />Reservoir had 511,000 acre-feet of active sto-
<br />rage and a water surface elevation of 7,481
<br />feet. The reservoir was gradually drawn down
<br />to el\wation 7,450 feet by March I, 1973, with
<br />a content of 315,000 acre-feet. During April-
<br />July 1973, inflow to Blue Mesa was 762,000
<br />acre-feet, with a 1973 water year total of
<br />1,020,000 acre-feet 0 This amount of water
<br />caused the reservoir to fill at elevation 7,519
<br />feet and an active storage of 829,300 acre-feet
<br />in July. During water year 1973, a minimum
<br />flow of 200 c.f.s. was maintained below Gun-
<br />nison Tunnel.
<br />The March I, 1973, forecast of the Apri 1-
<br />July 1973 inflow to Blue Mesa was 780,000
<br />acre-feet. The flood control diagram showed
<br />that the reservoir could have remained full the
<br />remainder of the snowmelt season; therefore,
<br />the operation of Blue Mesa did not include re-
<br />leases for flood control. (Chart 3)
<br />On May II, 1973, Blue Mesa releases were re-
<br />duced to zero in order to reduce flooding of the
<br />agricultural area near Delta, Colorado. All in-
<br />flow to Blue Mesa was stored until mid-April when
<br />the gain of the river below the Curecanti Unit be-
<br />gan to subside. Flows in the Delta area were held
<br />to a maximum of about 9,000 c. 1.s., thus reduc-
<br />ing the peak by about 5,000 coLs.
