(100-300 cfs). It was connected to the river by a side channel in May, <br />received some of its water from groundwater sources, and had no emergent <br />vegetation (Appendix E; Tables E.3. and E.4.). <br />White River. A potential (historical) of 634 acres (257 ha; 2 sites) of <br />bottomland habitat was available adjacent to the White River (rm 0-93 [rkm 0- <br />37.6]) in 1993 (Appendix D; Table D.1.). Of this total, 515 acres (208 ha; 2 <br />sites) were flooded during the May high-water flow period, and 18 acres (7 ha; <br />1 site) were inundated during the September low-flow period. <br />The oxbow downstream of Highway 65 (rm 92 [rkm 148]) was inundated from <br />May through September, whereas the confluence of the White and Green rivers <br />(rm 0-3 [rkm 0-5]), with the greatest bottomland area, was dry in September. <br />Both the oxbow and confluence sites were connected to the river in May and the <br />oxbow site was connected to the river in September (Appendix E; Tables E.5. <br />and E.6.). Both sites received some of their water from groundwater sources, <br />but only the confluence site had emergent vegetation. The oxbow site was a <br />flooded side-channel and the confluence site was a floodplain terrace. <br />Colorado River. There were 110 bottomland habitat sites with a <br />potential (historical) of 12,315 acres (4,984 ha) along the Colorado River (rm <br />0-241 [rkm 0-388]) in 1993 (Appendix D; Table D.2.) Of this total, 2,472 <br />acres (1,000 ha; 101 sites) were inundated during the May and June high-water <br />flow period and 1,135 acres (459 ha) in the September low-water flow period. <br />There were three distinct areas where bottomland habitats were <br />concentrated. These were usually in large floodplain areas near agricultural <br />centers. The first area was the stream reach between Debeque and Rifle, <br />Colorado (rm 203-240 [rkm 327-386]); 2,248 acres [910 ha]), the second was the <br />stream reach in the Grand Valley between Loma and Palisade, Colorado (rm 152- <br />185 [rkm 245-298]; 4,564 acres [1,847 ha]), and the third area between the <br />McGraw and Hotel Bottoms and the Cisco Boat Landing (rm 99-110 [rkm 159-177]; <br />1,214 acres [491 ha]). Moab Slough (rm 62-64 [rkm 100-103], downstream of <br />these three areas near Moab, Utah, is the largest single bottomland area along <br />the Colorado River encompassing approximately 875 acres (354 ha)(Figure 5). <br />Bottomland areas in canyon-bound stream reaches of the Colorado River <br />were typically small in acreage. These areas included Canyonlands National <br />Park downstream of Moab, Utah (rm 61-0 [rkm 98-0]), Moab Canyon (rm 64-77 [rkm <br />103-124]), Hittle Bottom to McGraw Bottom (rm 88-99 [rkm 142-151]), Ruby and <br />Horsethief canyons (rm 131-152 [rkm 211-245]), and Debeque Canyon (rm 188-204 <br />[rkm 303-328]). <br />Seventy-one percent (71 sites) of the 100 sites flooded in May had a <br />hydrological connection to the river, whereas 77% (43 sites) of the 56 sites <br />still wet in September were connected to the river (Appendix E; Tables E.7. to <br />E.13.) Although 71 sites were inundated during May and June, 26 sites had <br />only one surface connection to the river and 15 sites had both an up- and <br />downstream surface connection. Twenty-one percent of the May flooded sites <br />received some water from gravity-fed (irrigation) water sources and 56% <br />17
