. ATTACHMENT 1 SUMMARY OF RECOVERY GOALS FOR COLORADO PIKEMINNOW, HUMPBACK CHUB, RAZORBACK SUCKER, AND BONYTAIL DOWNLISTING COLORADO PIKEMINNOW (Green River, Upper Colorado River, and San Juan River Subbasins) DELISTING DEMOGRAPHIC CRITERIA (*self-sustaining with natural recruitment) Over a 5-year monitoring period: . Maintain the upper basin metapopulation . Maintain populations in Green and upper Colorado River subbasins (Uno net loss") . Green River subbasin population> 2,600 adults* . Upper Colorado River subbasin population> 700 adults* Establish 1,000 age-5+ subadults in San Juan River RECOVERY FACTOR CRITERIA I. Beneficial flow regimes identified, implemented, evaluated, and revised 2. Passage over Redlands and Grand Valley diversions continued 3. Modification ofPrice-Stubb and Government Highline dams to allow passage initiated 4. Barriers on San Juan River identified, evaluated, and modifications to allow passage initiated 5. Investigations initiated on modifying Aspinall Unit releases to increase water temperatures 6. Measures identified to minimize entrainment of subadults and adults at diversion structures 7. Overutilization reevaluated and, if necessary, actions identified to ensure adequate protection 8. Effects of diseases and parasites reevaluated and, if necessary, actions identified to ensure adequate protection 9. Nonnative fish stocking procedures developed, implemented, evaluated, and revised 10. Control programs for small-bodied nonnative fishes in nursery backwaters developed and implemented to identify necessary control levels II. Channel catfish control programs developed and implemented to identify necessary control levels 12. Northem pike control programs developed and implemented to identify necessary control levels 13. Mechanisms determined for legal protection of habitat 14. Elements of conservation plans identified 15. Hazardous-materials spills emergency-response plans reviewed and modified as necessary 16. Locations of petroleum pipelines in 100-year floodplain of critical habitat identified and need for emergency shut-off valves assessed 17. Actions identified for remediation of groundwater contamination at Atlas Mills tailings pile 18. Effects of selenium reevaluated and, if necessary, actions identified to reduce deleterious levels DEMOGRAPHIC CRITERIA (*self-sustaining with natural recruitment) For 7 years beyond downlisting: . Maintain the upper basin metapopulation . Maintain populations in Green and upper Colorado River subbasins (Uno net loss") . Green River subbasin population> 2,600 adults* . Upper Colorado River subbasin population> 1,000 adults* OR Upper Colorado River subbasin population> 700 adults* and San Juan River population> 800 adults* RECOVERY FACTOR CRITERIA I. Necessary flow regimes provided 2. Passage over Redlands and Grand Valley diversions continued 3. Modification ofPrice-Stubb and Government Highline dams to allow passage completed 4. Barriers on San Juan River modified to allow passage 5. Aspinall Unit releases modified, if determined feasible and necessary 6. Devices installed and/or measures implemented at diversion structures to minimize entrainment of subadults and adults 7. Adequate protection from overutilization attained 8. Adequate protection from diseases and parasites attained 9. Nonnative fish stocking procedures finalized and implemented 10. Identified levels of nonnative fish control in nursery backwaters attained I I. Identified levels of channel catfish control attained 12. Identified levels of northern pike control attained 13. Necessary habitat legally protected in perpetuity 14. Conservation plans developed and implemented, and necessary agreements executed 15. Emergency-response plans for hazardous-materials spills implemented 16. Emergency shut-offvalues installed on problematic petroleum pipelines 17. Groundwater contamination remediated at Atlas Mills tailings pile 18. Deleterious levels of selenium contamination reduced
