<br />FLAMING GORGE RESERVOIR
<br />(GREEN RIVER)
<br />
<br />Water Year 1993
<br />
<br />The elevation of Flaming Gorge Reservoir at the beginning
<br />of water year 1993 was 1835.9 meters (6023.6 f~t) with 3,831
<br />million cubic meters (3,106,000 acre-feet) of live storage (83
<br />percent of capacity). At the end of the water year, the
<br />elevation was 1838.8 meters (6033.2 feet). Live storage on
<br />September 30, 1993, was 4,281 million cubic meters
<br />(3,471,000 acre-feet), 93 percent of capacity.
<br />
<br />Unregulated inflow into Flaming Gorge Reservoir for water
<br />year 1993 was 1,838 million cubic meters (1,490,000
<br />acre-feet), 90 percent of normal. Actual regulated inflow was
<br />1,634 million cubic meters (1,325,000 acre-feet). The April
<br />through July runoff was 1,275 million cubic meters (1,034,000
<br />acre-feet) or 85 percent of the Ipng term average. With this
<br />near average inflow, Flaming Gorge gained 450 million cubic
<br />meters (365,000 acre-feet) of storage in water year 1993.
<br />
<br />In 1993, Flaming Gorge was operated in accordance with the
<br />Fmal Biological Opinion on the Operation of Flaming Gorge
<br />(FBOFG), issued in November 1992.

<br />The FBOFG outlines the reservoir operations during the
<br />spring, summer, and early fall months which may provide an
<br />improved habitat for endangered endemic species of fish.
<br />To accommodate the FBOFG, releases of 122 cubic meters
<br />per second (4,300 cubic feet per second) were planned to be
<br />released from Flaming Gorge for four weeks in late May and
<br />early June to coincide with the peak flow of the Yampa
<br />River. However, due to the unexpected high runoff from the
<br />Yampa River, these releases were not maintained for the
<br />entire four weeks so that flooding near Jensen,.Utah could
<br />be m;nimi7ed. During this period, releases which were
<br />jointly agreed upon by Reclamation, the Fish and Wildlife
<br />Service, and Western Area Power Administration, were
<br />made so that flows in the Green River near Jensen would
<br />not exceed 566 cubic meters per second (20,000 cubic feet
<br />per second). After completion of the spring runoff, flows
<br />between 38.2 and 51.0 cubic meters per second (1,350 and
<br />1,800 cubic feet per second) were maintained at the Green
<br />River near Jensen, Utah. Under the terms of the FBOFG,
<br />1993 met the flow requirements for the high flow year.
