<br />000184 <br /> <br />Program should coordinate with UDWR, Reclamation, and the Service to manage the <br />floodplain to benefit the razorback sucker and not negatively impact waterfowl <br />management. <br /> <br />4. Coordinate floodplain restoration and management with Ouray National Wildlife Refuge. <br /> <br />The majority of potential floodplain depression habitat is found in the Ouray National <br />Wildlife Refuge. The Recovery Program should initiate coordination, as necessary, with <br />ONWR to manage key floodplains to benefit the endangered fishes and not negatively <br />impact the goals and objectives of the ONWR Comprehensive Conservation Plan. <br /> <br />5. Continue to manage restored floodplains. <br /> <br />The Recovery Program has initiated restoration on eight sites: Bonanza Bridge, <br />Horseshoe Bend, The Stirrup, Baeser Bend, Above Brennan, Johnson Bottom, Leota <br />Ponds, and Old Charlie Wash. These sites should be managed and evaluated for <br />effectiveness as habitat for all life stages of razorback sucker and bonytail. <br /> <br />6. Continue stocking of hatchery razorback sucker and bonytail. <br /> <br />Release of hatchery razorback sucker and bonytail is vital to species recovery. These fish <br />augment sparse wild populations and provide the foundation for a self-sustaining <br />population. Stocking also provides fish in the wild to better assess best management <br />strategies for floodplains. <br /> <br />7. Assimilate and synthesize results of fish growth and survival in floodplains. <br /> <br />Studies of growth and survival of hatchery razorback sucker and bonytail have been on- <br />going since 1996. More recent and on-going studies address pertinent issues of best size <br />at stocking and survival under varying levels of nonnative fish densities. The sum of <br />information gathered from these studies needs to be assimilated in order to determine the <br />status of knowledge and the need for additional studies. Possibly, there is sufficient <br />information available to apply best strategies of growth and survival learned at one <br />floodplain site to other sites, precluding the need for comprehensive growth and survival <br />studies at each site. <br /> <br />8. Evaluate geomorphic and hydrologic characteristics of entrainment. <br /> <br />Conditions that maximize entrainment of larval razorback sucker in floodplains are not <br />well known. A single study should be implemented to assess conditions at key floodplain <br />sites in order to incorporate necessary elements into design of levee breaches and <br />inlet/outlet control gates. <br /> <br />9. Use existing programs to monitor response by razorback sucker and bonytail. <br /> <br />2003 Report Recommendations, <br />
