<br />TN~ <br /> <br />I. Identify bottomlands adjacent to upper Colorado River basin <br />mainstem rivers representing potential endangered fish habitat. <br /> <br />2. Classify the bottomlands identified according to potential <br />value for endangered fish recovery. <br /> <br />3. Rank mainstem bottomlands by their perceived value to <br />endangered fish recovery. <br /> <br />The end product will be a listing of mainstem flooded bottomlands <br />classified as to size, rate and duration of flooding, fish access, <br />permanency, vegetation type, and other non-biological criteria <br />that will enable us to rank their value in contributing to <br />endangered fish recovery. Some of the possible non-biological <br />criteria might include determining land ownership, status, access, <br />ability to install water control structures, etc. These non- <br />biological criteria will develop and further explored at a later <br />date. This project will limit its scope to include only those <br />bottomlands which represent a potential for use by endangered <br />fishes and will not constitute an inventory of all wetlands and <br />bottomlands adjacent to the major river system. In addition, the <br />project will provide plans for the orderly development and <br />acquisition of flooded bottomlands. <br /> <br />IV. Study area <br /> <br />The study area will include habitats adjacent to the mainstem <br />rivers in the upper Colorado River basin: Colorado River <br />downstream from Rifle to the Confluence with the Green River; <br />Gunnison River downstream from Austin to the confluence with the <br />Colorado River; Vampa River from Cross Mountain Canyon downstream <br />to the confluence with the Green River; Green River downstream <br />from Brown's Park to the confluence with the Colorado River; White <br />River downstream from Taylor Draw Dam to the confluence with the <br />Green River. <br /> <br />V. Study methods/approach <br /> <br />I. Identify bottomlands adjacent to mainstem upper Colorado River <br />basin rivers containing potential endangered fish habitat. <br /> <br />a. Identify and assemble existing information, such as <br />topographical maps, videography, and aerial photos. <br /> <br />b. Formulate a list of bottomlands that may contribute to <br />endangered fish recovery. <br /> <br />c. Conduct low cost aerial flights to verify and complete <br />inventory. <br /> <br />d. Investigate the use of existing classification systems <br />for identifying bottomlands representing endangered fish <br />habitat. <br /> <br />2 <br />
