Table AI. Continued. Studies Project 143 (continued) Physical evaluation of floodplain habitat (project Cap-6HYD) Western aerial photography of 2005 peak flow Western backwater topography study USGS razorback spawning bar study Utah State University lReclama tion channel monitoring studies Study Goal and Objectives Objectives 2. 1. Collect adult pike and take dorsal flesh samples at each reservoir and in the Yampa River. 2. Utilize stable isotope analysis to evaluate diet composition. Goal To restore floodplain habitats in a manner that will benefit endangered fishes, minimize potential adverse effects, and be cost-effective. Objectives 1. To determine bankfull flood flows, with and without excavation; 2. To determine area of inundation as a function of flow, with and without excavation; 3. To compare historical versus existing frequency, duration, and timing of flood flows, with and without excavation; 4. To characterize pre-restoration baseline channel and site morphology, and post-restoration morphology; 5. To develop design options for enhancing floodability; 6. To oversee construction activities; 7. To monitorresults Goal Document areas and elevations of inundation for floodplains with aerial photography during spring peak flows. Ob1ectives 1. Determine areas of floodplain inundation at various river flows. 2. Determine approximate elevations of inundation with various river flows. Goal Evaluate effect of seasonal and daily flow variability on backwater availability and quality. Objectives 1. Monitor backwater dimension and depth as affected by seasonal and daily flow variability. Goal Assess effect of river flows on sediment deposition at the razorback sucker spawning bar on the Green River. Objectives 1. Measure sediment deposition on spawning cobbles at various river flows. Goal Describe geomorphic changes with flow, sediment transport and vegetation encroachment.
