Reclamation believes that the proposed water contracts will not have an affect on the Whooping Crane or its required habitat. 3.6.2.1.3 Black-footed ferret The Black-footed ferret was first listed by the Service in 1967. The species inhabits semi-arid grasslands and mountain basins. Recognized as an obligate associate to prairie dogs that constitute their primary food source and provide burrows for shelter and breeding. This species may occur in active prairie dog colonies that contain suitable burrow4ensiti~s and size. Ferrets breed from March to May. Kits are born late May to early June and.remain underground until late June or early July. (BLM, 2001 (Kerns River) There are no recent reports of this species, which is closelyasso~iated with prairie dog towns, in the proposed carriage contract areas. The proposedc;ohtract area lands have previously been converted to agricultural activities which have resulte<;i in decline of prairie dog communities Reclamation believes that there will be no affect-to tliei,Black-footed ferret or to its habitat resulting from the implementation of these proposed wateg,carriage contracts. 3.6.2.1.4 Mancos Milkvetch The Mancos rnilkvetch was listed by the Service as endangered on June 27, 1985 (federal . . . . - - . . .

Colorado Pikeminnow-- This large, predaceous species is adapted to seasonally variable flows, high silt loads and turbulence, low food base, and changing river subsystems. Y oung-of-the-year prefer shallow backwaters, while adults and older juveniles utilize pools, eddies, and deep runs. The Colorado Pikeminnow spawn from June to August. Razorback Sucker- Species tends to be most abundant in calmer, "flatwater" river, rather than higher velocity canyon river flows. Species may spawn in a variety of flow conditions (from rivers to impoundments). Some fish will return to the same spawning locations. The species 19
