Abstract

Activities continue in an effort to improve the status of many native fishes of the Upper Colorado River Basin. These activities are guided principally by four programs: the Upper Colorado River Endangered Fish Recovery Program, the San Juan River Basin Recovery Implementation Program, the Range-wide Conservation Agreement for the Colorado River Cutthroat Trout, Oncorhynchus clarkii pleuriticus and the Range-wide Conservation Agreement and Strategy for the roundtail chub, Gila robusta, bluehead sucker, Catostomus discobolus and flannelmouth sucker, C. latipinnis. The two recovery programs, which collectively work towards the recovery of Colorado pikeminnow, Ptychocheilus lucius, razorback sucker, Xyrauchen texanus bonytail, G. elegans and humpback chub, G. cypha use the protection of in-stream flow, habitat restoration, nonnative fish control, propagation, life history monitoring, and information and education to bring benefits to the four Á¢â‚¬Å“big river fishes.Á¢â‚¬Â A summary of the recently completed Á¢â‚¬Å“Sufficient Progress ReportsÁ¢â‚¬Â for both the San Juan and upper Colorado River Recovery programs will be presented. Tasks to assist the species under Conservation Agreements included multiple remote sensing projects to determine native fish utilization of tributaries throughout the basin; tamarisk control and other habitat restoration; distribution and density monitoring throughout their ranges; and renovation of trout streams and reintroduction of the Colorado River cutthroat trout continues in Colorado, Utah, and Wyoming.
