1. Colorado squawfish in the Colorado river between Palisade and the Colorado - Utah state line. 2. razorback sucker in both the Colorado and Green river subbasins. 3. bony tail chub in yet to be identified locations in the Upper Basin: 4. humpback chub at locations not presently used by those species. but yet to be identified. The Colorado squawfish population in the Colorado River below the Gunnison appears to be very low. The razorback sucker is spawning. but no recruitment into the population has taken place. apparently as a result of predation. Until the predation problem can be dealt with directly. maintenance of brood stocks and stocking of razorback sucker will probably be necessary to maintain a population in the Upper Basin. Bony tail chub are practically non-existent in the Upper Basin. Locations need to be identified where bony tail populations can be reestablished. At some locations. humpback chub populations appear to be doing well and there is no need for augmenting those locations: however. the populations may need to be augmented in the Green and Yampa Basins. Water users realize that stocking will have to be used intelligently in the Upper Basin. Stocking should be used to support the attainment of specific recovery goals for each species. along with the other recovery elements. Role of Water Acquisition In the process of negotiating the Recovery Implementation Program. water users agreed to support acquisition of water for endangered fishes based on the following conditions: 1) that the water be appropriated in accordance with state water laws: 2) that the quantity of water appropriated is demonstrated to be needed for recovery of the endangered fish. The Recovery program calls for appropriation of water for endangered fishes. and transfer of acquired water to the Colorado Water Conservation board. In the case of either appropriation or acquisition. water will be protected under the Colorado instream flow law. The Colorado Water Conservation board may appropriate or acquire water if the statutory criteria for appropriation of instream flows are satisfied. Generally these criteria are 1) the water is the minimum amount needed to protect the natural environment 2
