! The report entitled "Endangered Fish Use and Flow Recommendations
for the Duchesne River, Utah" was approved by the Biology Committee on
9/29/03,

! This task is ongoing but an initial assessment has been made and
potential sources identified, Legal and physical availability of water to
meet the 2003 flow recommendations is currently being assessed by the
State of Utah and members of the Duchesne River Working Group
(DRWG), Strawberry VaHey Project, Daniels Diversion and Coordinated
River Operations have been identified as having high potential for
providing water to help meet flow recommendations, Recommended
completion date for this task is December 2004,

Modeling completed for determination of water availability from
Strawberry and Daniels,

XDue to delays in finalizing the flow recommendations, a completion date
of 12/2005 is now reconunended for the DRWG to develop agreements for
use of any available water from the Daniels Diversion for instream flows
in the lower Duchesne River.

X Coordinated reservoir operations study was scheduled for completion in
June 2003 and should be brought to completion as soon as practical so that
