RECLAMATION RELEASES NEW TRINITY RIVER FLOW SCHEDULE

A Ninth Circuit Court ruling on April 23 significantly increased the
volume available to the Trinity River.  The Court's ruling came as a
result of a request from the Hoopa Valley Tribe.  In December 2002, U.S.
District Court Judge Oliver Wanger limited the available volume of water
to 453,000 acre-feet pending completion of a final Supplemental
Environmental Impact Statement/Report.  The Ninth Circuit Court's
ruling, in response to the emergency motion, increased that volume to
647,000 acre-feet for this year.

The newly revised 2004 flow schedule will be finalized by the
Department of the Interior, based on a recommendation made by the
Trinity Management Council to achieve a wide variety of physical and
biological objectives.  This schedule will not only benefit smolt
(juvenile salmon and steelhead) growth and survival in late spring and
early summer, but will also achieve substantial geomorphic benefits by
flushing large accumulations of fine sediment that have been deposited
over the past two years, move and redeposit gravel, and scour 1-2 year
old riparian vegetation that has re-encroached along the channel's edge,
all of which will improve habitat conditions throughout the system.

Under the newly approved flow schedule, current releases from Lewiston
Dam to the Trinity River will continue at 300 cubic feet per second
(cfs) through Tuesday, May 4, ramp up to 2,500 cfs by Thursday, May 6,
and then continue up to 6,000 cfs by Sunday, May 16.  The schedule calls
for these releases to continue at 6,000 cfs from May 16 through Tuesday,
May 25, gradually ramping down to 2,000 cfs by June 18, and finally
reaching the summer base level of 450 cfs by July 22.

The new flow release schedule is available online at Reclamation's
Central Valley Operations (CVO) web site at www.usbr.gov/mp/cvo
