place at meetings of the "Flaming Gorge Working Group". A Working
Group meeting was held August 2 in Heber, Ut. The next Working
Group meeting is scheduled for October 23 at 10 am in Vernal, Ut.

ASPINALL July unregulated inflow into Blue Mesa was 92,700
acre-feet or about 72 percent of average. The inflow into the
Aspinall Unit for the April through July period was 830,000
acre-feet or 119 percent of average.

Current inflow into Blue Mesa is about 1,050 cfs. Diversions
through the Gunnison Tunnel are currently about 927 cfs, releases
from Crystal Dam are about 1,822 cfs, leaving approximately 895 cfs
in the river.

On April 18, 1996 a public meeting was held and the operation plan
for April through August 1996 was set. The next operation meeting
.will be held August 22, 1996 at the USBR office in Grand Junction.
Anyone needing further information about this meeting, please
contact Ed Warner in the Grand Junction Area Office at (970)
248-0654.

NAVAJO July inflow into Navajo was only 35,900 acre-feet
approximately 20 percent of average. Precipitation in the San Juan
Basin has been very low the past few months. This has affected the
expected inflow into Navajo for the April through July runoff
period. The April through July inflow into Navajo was only 239,000
acre-feet or 31 percent of average.

Currently releases from Navajo are 605 cfs. With the low amount of
inflow forecasted for 1996, releases will probably remain near 605
cfs through the rest of the water year.

The next operation meeting will be held in March 1997. Anyone
needing information about daily operations please contact Don
Fazzan or Rege Leach at the Durango Office at [phone].

GLEN CANYON - This year's April - July unregulated runoff into Lake
Powell was 7.3 MAP, 94 percent of average, a drop from the 115
percent forecasted a few months ago. July's inflow was only 81
percent of average, a result of dry conditions throughout the
basin. Inflow through the fall months is also expected to remain
about 80 percent of average. The peak reservoir elevation this
year was 3688.31 feet, about 12 feet below full capacity.

This summer's releases have been similar to the rest of the year,
averaging about 16,000 cfs with fluctuations between 13,000 and
