! X Flaming Gorge being re-operated under the 1992 Biological Opinion,
but EIS on reoperation to implement the revised flow recommendations
has experienced continued delays,

X Public meetings and appropriation policy not done in FY 03 (won't
held/implemented until 04/05, pending completion of the EIS and new
biological opinion), Recommend completion of new policy after the
Record of Decision for the Flaming Gorge EIS (estimate December 2004)

X Price Ri\ler winter flows report delayed one year (now due to
coordinator May 2004)

! Floodplain acquisition and levee removal strategy are complete and
operation, maintenance and evaluation of sites is now incorporated into
Green River subbasin floodplain management plan,

! Flows were high enough in 2003 for entrainment study; beads used since
larvae not available, beads were entrained at both the Bonanza Bridge and
Above Brennan sites,

! Larval razorback sucker and bonytailagain survived in the presence of
nonnative fishes in several wetlands, Adult bonytail spawned in at least
two wetland sites,

! Once again, some razorback sucker captured in the Green River in 2003
were from those originally stocked into floodplain wetlands suggesting
voluntary movement from the floodplain to the river and subsequent
survival and recruitment.

Design and construction of the fish screen at the Tusher Wash Diversion
was previously delayed due to a water rights dispute, This dispute has been
settled by the Utah Supreme Court and construction is scheduled for FY
07-08,

! A total of22 northern pike were removed from the middle Green River
(suggests a depletive effect from previous years, since 42 pike were
removed in 2002 and 248 pike were removed in 2001),

X Revised report on cyprinid removal in lower Colorado and lower Green
rivers still overdue; now expected in May 2004,

Some chmmel catfish were removed from the middle Green River,
however, the original study design was only partially implemented due to
low flows,
