J 1 initial stages and no information is available at this time. Habitat use by hatchery-reared adult fish (Bradford and Garden 2000) and predation on ' this species by ictalurids (Marsh and Brooks 1989, Slaughter et a1.2002, Young and Marsh 1990) has been investigated in this subunit. ' Applicable Recovery Goals and Management Strategies: ' Recovery Goal: Maintain self-sustaining populations while moving toward recovery. (See Lake Mohave Subunit and Appendix I for downlisting and delisting criteria). ' h Management Strategies: This Recovery Goal will be met throug the use of Strategy 1: Augmentation and Strategy 2: Isolated ' Habitat. GIlr4 RIVER SUBUNIT Background Information ' Location: Gila, Graham, Greenlee, Pinal, and Yavapai Counties AZ Geographic Boundary: The Gila River from the Arizona-New Mexico ' border to Coolidge Dam, including San Carlos Reservoir. The Salt River from the US60/SR77 bridge crossing to Roosevelt Diversion Dam. The ' Verde River from Sycamore Canyon to Horseshoe Dam including Horseshoe Lake . Description of Habitats Available: These three rivers have upper reaches without controlled flows but with some degree of diversion for municipal and agricultural purposes. They include riffle, run, and pool habitats with ' shoreline eddies and bars and some braided channel features. Small tributaries to the Salt and Verde are included in the reach, with more significant flows coming into the Gila River through the San Francisco River drainage in addition to that from smaller tributaries. These 1 tributaries provide riffle, run, and pool habitats, and shallow, sheltered areas. The Gila River subunit includes amedium-sized reservoir at the terminus of the sub-reach. Horseshoe Lake and San Carlos Reservoir ' are water storage reservoirs that fluctuate in response to water releases for downstream users. Both reservoirs have a history of nearly drying up _. ' ~ 32 1
