<br />002840 <br /> <br />. Prepare a white paper on the temperature issues surrounding Navajo Dam releases and <br />the endangered fish, <br /> <br />. Determine spawning habitats and locations using radiotelemetry, <br /> <br />. Determine the status and success of all razorback sucker life stages as reproduction <br />increases and the population expands, <br /> <br />Objective 4: Monitor the availability, creation, and maintenance of key habitats and incorporate this <br />infonnation into the flow recommendations. <br /> <br />. Conduct monitoring in accordance with the Monitoring Plan <br /> <br />Objective 5: Evaluate potential hybridization between tlannehnouth sucker and razorback sucker. <br /> <br />Objective 6: Control nonnative fish in the San Juan River, <br /> <br />. Continue with nonnative fish mechanical removal during monitoring and research activities, <br /> <br />. Evaluate other potential nonnative fish control measures (e,g., weirs, selective passage <br />structures, reduced levels of Lake Powell, flow manipulation). <br /> <br />. Develop measurable objectives and methods for assessing and maintaining effectiveness <br />of removal efforts. <br /> <br />. Develop nonnative fish stocking and baitfish policies in conjunction with the affected states. <br /> <br />2. Restore a Demographically Viable Colorado Pikeminnow <br />population in the San Juan River <br />Studies during the 7-year research period identified a small population (about 20 adults) of wild <br />Colorado pikeminnow in the San Juan River below Shiprock. Experimental stocking of YOY <br />proved successful and several hundred or more subadult Colorado pikeminnow now inhabit the <br />river below Shiprock. They may start to spawn with the wild population in the next few years, The <br />population below Shiprock needs to be studied to determine if the stocked fish reproduce <br />successfully and how they interact with the wild population. The studies also showed that habitat <br />for Colorado pikeminnow occurs in the San Juan River between Shiprock and the mouth of the <br />Animas River (upper San Juan River). Colorado pikeminnow need to be established in the upper <br />San Juan River, which is part of Critical Habitat for this species, <br /> <br />5-3 <br /> <br />Program Evaluation Report <br /> <br />September 2000 <br />
