In order to acquire adequate information needed to determine the impacts of the proposed Susitna Hydroelectric Project and to design proper mitigative strategies, a two-phase data collection program has been developed. This manual addresses Phase I (July 1, 1980-December 31, 1981) procedures to be conducted within the Susitna River Valley. Technical procedures are provided for these studies: Adult Anadromous Fisheries Studies, Resident and Juvenile Anadromous Fisheries Studies, and Aquatic Habitat and Instream Flow Studies.

"This Phase II (July 1, 1982 to June 30, 1983) procedures manual addresses changes, deletions, and additions to the Phase I (July 1, 1981 to June 30, 1982) procedures manual."--Page 3.

To insure adequate information is available to determine the impacts of the proposed hydroelectric project and to design proper mitigative strategies, a two-phase data collection program has been developed. This manual addresses Phase I (July 1, 1980-December 31, 1981) procedures to be conducted within those study areas.

Presentation of data from extensive studies concerned with the distribution and abundance of fish populations and their aquatic habitat in portions of the Susitna River, Alaska, which would impacted by the proposed Susitna Hydroelectric Project.

This is a draft version of a procedures manual for the Juvenile Anadromous Habitat Study (JAHS), whose purposes are (1) to study seasonal distribution and relative abundance of resident and juvenile anadromous fishes in the Susitna River (downstream of Devil Canyon) and (2) to characterize seasonal habitat requirements of selected resident and anadromous fishes in the study area. The JAHS study consists of three projects are: Adult Anadromous Fisheries Project, Resident and Juvenile Anadromous Fisheries Project, and Aquatic Habitat and Instream Flow Project. For each project, the manual specifies the technical procedures, data processing, and quality control.
