~ 1-1 1.0 INTRODUCTION This document reports on the occurrence of threatened and endangered fishes in the Upper Colorado River in the vicinity of a small hydro-electric power project proposed by Eric R. Jacobson of Grand Junction, Colorado. The project, known as the Jacobson Hydro No.1 (JH-1), is located on the main Colorado River (river mile 188.2), about 1 mile upstream from the 1-70 Highway bridge at Palisade, Colorado. The project sponsor plans to reactivate an existing channel diversion and turbine facility located at the Price-Stub Dam (PSD). The power canal intake is located on the northwest river bank. Up to 2077 cubic feet per second (cfs) would be diverted from the river for the proposed hydro-project. Representatives of the U. S. Fish and Wildlife Service (USFWS) and the Colorado Division of Wildlife (CDOW) have expressed concerns that this hydro-project may impact federal and state threatened and endangered (T&E) fishes that may occur in the vicinity of the intake canal. These concerns are noted in the first addendum to the license application filed by Eric R. Jacobson (1983). The fishes of primary concern are the three endangered species of the Upper Colorado River Basin; humpback chub (Gila cypha), bony tail (Gila elegans), and Colorado squawfish (Ptychocheilus lucius). These species are protected by the Endangered Species Act (ESA) of 1973, as amended, as well as by the State of Colorado. In addition, the razorback sucker (Xyrauchen texanus) is considered a 'candidate' species under the ESA but, as such, receives no protection from the act. The species is protected by the State of Colorado under the classification of 'threatened'. 1.1 Permit Deficiencies This document is written to address deficiencies noted by the Federal Energy Regulatory Commission (FERC Project 4515) in response to the Jacobson
