Hydro No.1 License Application dated October 1983. The deficiencies cited
and briefly discussed in Exhibit E of the FERC response are as follows:
1. A description of threatened and endangered species in the project
area. Any larval fish studies to determine the occurrence of threatened and
endangered species should be coordinated with the U.S. Fish and Wildlife
Service.
2. A description of impacts to threatened and endangered species that
would result from project operation.
3. A description of proposed mitigative measures to minimize project-
related impacts to threatened and endangered species, including: (i)
functional design drawings of any fish passage facilities; (ii) a
description of operating and maintenance procedures; (iii) a construction
schedule for any proposed facilities; (iv) an estimate of the costs of
construction, operation, and maintenance; (v) a drawing showing the location
of any proposed facilities.
This document addresses items 1 and 2 above. It was prepared to
respond to the specific questions and information requirements developed for
the project by the USFWS Endangered Species Team (Office of Endangered
Species) offices in Salt Lake City, Utah and Grand Junction, Colorado and
reflected in the FERC application. This document was prepared exclusively
by Ecosystem Research Institute (ERI) for Eric R. Jacobson.

1.2 Objectives
The objectives of this investigation are to :
1. Document the presence or absence of state and federal threatened and
endangered as well as game fishes in the Colorado River in the vicinity of
the proposed hydro-electric project.
2. Determine seasonal, temperature, and nocturnal/diurnal drift
