Study Goals, Objectives, End Product <br /> <br />A. Goal: To restore or enhance flood plain functions for recovery <br />of endangered fishes in the upper Colorado River basin. <br /> <br />B. Objectives: <br /> <br />The long-term intent of the Flooded Bottom Lands Restoration Program is to <br />restore various off-channel habitats which can behave as naturally as <br />possible as they did historically, and which will reqUire minimal O&M <br />costs. The short-term goal is to stabilize razorback sucker populations, <br />and improve conditions to maximize recruitment and provide for long-term <br />persistence of razorbacks and other native fishes. However, in some <br />stream reaches, simply reconnectin9 off-channel habitats of the flood <br />plain to the mainstem river during high flows may not be adequate to <br />recover razorback sucker. It is pOSSible that other factors are limiting <br />the species and causing recruitment failure. Assessment of limiting <br />factors is pivotal to determining if recovery is feasible in certain <br />stream reaches of the Upper Colorado and Gunnison rivers, and in guiding <br />future flood plain efforts and activities at other sites. Initially, some <br />
