<br />At the end of September 1973, Blue Mesa
<br />Reservoir had 716,000 acre-feet of active storage
<br />and a water surface elevation of 7,506 feet. The
<br />reservoir Was drawn down to elevation 7,4.t I feet
<br />by April I, 1974, with a content of 267,000
<br />acre-feet. During April-July 1974, inOow to Blue
<br />Mesa was 555,000 acre-feet, with a 1974 water
<br />year total of 767,000 acre-feet. The seasonal high
<br />for the reservoir was elevation 7,497 feet and an
<br />active storage of 640,000 acre-feet. During water
<br />year 1974, a minimum flow of 200 ft3/s was
<br />maintained below Gunnison Tunnel.
<br />
<br />The March I, J 974, forecast of the April-July
<br />1974 inflow to Blue Mesa was 800,000 acre-feet.
<br />The flood control diagram showed that the
<br />reservoir could have remained full the remainder
<br />of the snowmelt season; therefore, the operation
<br />of Blue Mesa did not include releases for Oood
<br />control. (Chart 3)
<br />
<br />During the period May I through
<br />September 30, 1974, Jow releases from Blue Mesa
<br />insured a flow of not more than 1,500 ft3/s in
<br />the Crystal Dam site area. Most of the spring
<br />runoff was stored behind Blue Mesa Dam.
