Releases from Flaming Gorge will then be adjusted to maintain a
flow of 1800 cfs on the Green River near Jensen, Ut.

In water year 1996, Flaming Gorge is again being operated in
compliance with the Final Biologieal Opinion for the operation of
Flaming Gorge Dam (FBOFGD). Water year 1996 is the last year in
the five year research period, through which recommendations for
winter and spring operations at the dam will be based.

Open forum discussions on Flaming Gorge operations have been taking
place at meetings of the "Flaming Gorge Working Group". The next
Working Group meeting will be held August 1 at 10:00 am in Heber,
Ut. For more information on the Working Group, contact Ed Vidmar

ASPINALL - May unregulated inflow into Blue Mesa was 355,900
acre-feet or about 166 percent of average. The forecasted inflow
into the Aspinall unit for the April through July period is
expected to be 820,000 acre-feet or 117 percent of average.

Current inflow into Blue Mesa is about 5,200 cfs. Diversions
through the Gunnison Tunnel have commenced, and are currently about
925 cfs, releases from Crystal Dam are about 2,100 cfs, leaving
approximately 1,175 cfs in the river.

On April 18, 1996 a public meeting on the operation of the Aspinall
Unit was held at the USBR office in Grand Junction. The operation

NAVAJO May inflow into Navajo was only 108,600 acre-feet
approximately 54 percent of average. Precipitation in the San Juan
Basin has been very low the past few months. This has affeeted the
expected inflow into Navajo for the April through July runoff
period. The runoff is expected to be only 300,000 acre-feet or 39
percent o~:.average.

curren~iy.,~feases from Navajo are 2,500 cfs. With the low amount
of inft6w....forecasted for 1996, releases will probably remain near
2,500 cfs through June 23, 1996. On June 24,1996, a ramp down of
releases will begin. This ramp down will be from 2,500 cfs to 600
cfs and will take about one week.
