<br />l)Mi3 <br /> <br />1, Green River <br />a. RM 0 to RM 47 (Canyonlands National Park: NPS) LOW PRIORITY <br />-Razorbacks: numerous larvae have been collected in this area: adult <br />distribution area, <br />-Squawfish: high density nursery area for young: juvenile high <br />concentration area, <br />-Approximately 1,870 acres of primarily floodplain terrace habitat: <br />levees, if any, are natural, <br />-Floodplain owned. managed, and protected by the National Park <br />Service: no floodplain development has occurred or is expected to <br />occur, <br />-Of, high biological importance for habitat restoration. However. <br />floodplain habitat restoration/enhancement options are limited to <br />either lowering the floodplain terrace elevations or restoring the <br />historical frequency and duration of spring flows exceeding 39,000 <br />cfs bank fu 11 , <br />-Conclusion: low priority geographic area because floodabil ity- <br />enhancement opportunities are limited: no floodplain development has <br />occurred nor is any future development anticipated, <br /> <br />b, RM 47 to RM 115 (Labyrinth Canyon: BLM) LOW PRIORITY <br />-Razorback: larvae likely drift through (and may use) this area: <br />adult distribution area, <br />-Squawfish: high density nursery area for young: juvenile high <br />concentration area: adult concentration area, <br />-Approximately 1,697 acres of primarily floodplain terrace habitat: <br />levees. if any, are natural, <br />-Floodplain almost entirely owned, managed, and protected by the <br />BLM: no floodplain development has occurred or is expected to occur, <br />-Possibly of high biological importance, However, floodplain <br />restoration/enhancement options are limited to either restoring high <br />spring flows or lowering floodplain terrace elevations, <br />-Conclusion: low priority geographic area because floodability- <br />enhancement opportunities are limited; no floodplain development has <br />occurred or is expected to occur, <br /> <br />c, RM 115 to RM 132 (Green River. Utah) HIGH PRIORITY <br />-Razorbacks: larvae drift through this area, and likely would use <br />flooded habitats if they were available: adult distribution area, <br />-Squawfish: high density nursery area for young: juvenile high <br />concentration area: adult concentration area, <br />-Approximately 700 acres of potential floodplain habitat: man-made <br />levees along much of the river. <br /> <br />10 <br />
