AccomDlishments:

Recovery Program participants accomplished several important objectives over the last year.

. Twenty-four ponds covering 51 acres were reclaimed in the Colorado and Gunnison river
floodplains to prevent nonnative fish escapement.

. The Recovery Program has made very good progress stocking hatchery-reared razorback
suckers and bonytail. Stocked razorbacks have appeared on the Green River spawning bar
in reproductive condition. Both stocked bony tail and razorback sucker have been found in
DesolatiorJGray Canyon area. Twelve new growout ponds totaling 15 surface acres were
completed in the last year.

. Three hundred and fifty northern pike were removed from the Yampa River. The Recovery
Program also is formulating plans for increased pike removal efforts in the future.

. The final Flaming Gorge synthesis report was approved by the Recovery Program and a
final draft report was completed for flow recommendations for the endangered fish in the
Gunnison and Colorado rivers. As these recommendations are implemented, it will result
in improved flows for the endangered fish,
