<br />~-1I <br /> <br />APPENDIX II <br /> <br />FLOODPLAIN HABITAT RESTORATION PROGRAM <br /> <br />Recommended Major Steps <br /> <br />I. Inventory of floodplain habitats. <br /> <br />Inventory primarily included those habitats between bankfull and 100-year <br />flood elevations, within the historically-occupied range of the <br />endangered fishes. An inventory was not conducted for floodplain <br />habitats between the thalweg and bankfull elevations. <br /> <br />2. Screening of floodplain habitats. <br /> <br />To develop an overview of the upper Colorado River basin, a wide variety <br />of geographically-scattered floodplain habitats have been screened for <br />contaminants, hydrology, geomorphology, biology, and land ownership, to <br />the extent possible. Based on preliminary screening results, and on <br />discussions at various meetings, screening of candidate restoration sites <br />will continue, but will be limited to contaminants and willingness of <br />landowners to cooperate. <br /> <br />3. Selection of river seqments for initial focus of acquisition and <br />restoration efforts. <br /> <br />Based on present or recent-past distribution and relative abundance of <br />razorback suckers, and site-screening results. <br /> <br />Mv recommendations: <br /> <br />a. Green River <br /> <br />I) Sand Wash (RM 216) to the razorback spawning bar (RM 311.5). <br /> <br />For acquisition, I would recommend focusing initially between <br />Brennan Bottom (RM 264) and Jensen (RM 305), where razorback <br />adults reside; razorback larvae are found; most of the <br />floodplain is privately-owned; there are several large <br />floodplain depressions; flood frequency and duration can be <br />controlled, in part, by Flaming Gorge operations; and <br />floodplain development has been relatively minimal and is, <br />therefore, reversible. Also, the draft "Flaming Gorge High <br />Flow Damage Assessment Report" (developed jointly by the U.S. <br />Fish and Wildlife Service, the Provo Area Office of the U.S. <br /> <br />I <br />
