2. conduction of a 5-year research program including implementation of
winter and spring research flows beginning in 1992 to allow for
potential refinement of flows for these seasons. This research
program will be based on the Five-Year Flaming Gorge Flow
Recommendations Investigations which.was,approved by the Recovery
Program (Appendix 6). The program provides for annual meetings to
refine seasonal flows based on research findings and water year
forecast. Except for specific research flows during the 5-year
research program, year-round flows in the Green River will resemble a
natural hydrograph described under element 1 of the reasonable and
prudent alternative;
3. determination of the feasibility .and effects of releasing warmer
water .during the late spring/summer period and investigation of the
feasibility of retrofitting river bypass tubes to include power
generation, thereby facilitating higher spring releases;
4. legal protection of Green River flows from Flaming Gorge Dam to Lake
Powell; and
5. initiation of discussions with the Service after the conclusion of
the 5-year research program to examine further refinement of flows
for the endangered Colorado River fish.
Thank you for your cooperation in the formulation of this opinion and your
interest in conserving endangered species.
