Construction of the Susitna Hydroelectric Project will eliminate or alter wildlife habitat in the Susitna River drainage. Mitigation will include designating specific lands for habitat compensation and then increasing and/or maintaining moose carrying capacity through habitat management techniques. Prescribed burning is the preferred techniques to increase the carrying capacity of most areas for moose.

This four-part document is a proposal submitted to Alaska Power Authority by HARZA-EBASCO Susitna Joint Venture for work on the Susitna Hydroelectric Project. The letter on corporate commitment explains that Harza Engineering Corporation and Ebasco Services Incorporated have formed this joint venture to provide engineering, project control, and regulatory and environmental studies for the proposed project. A transmittal letter to Alaska Power Authority, the joint venture agreement, Amendment no. 1 to the agreement, and resumes of personnel comprise volume 1, binder 1. Tasks with associated task and subtask numbers are included in volume 1, binder 2.

Flow duration curves derived for natural and with-project (Susitna Hydroelectric Project) conditions for the Susitna River, Alaska.

"The objective of these studies is to determine the effect of the proposed Watana and Devil Canyon Dams on river ice processes and the corresponding water surface elevations during the winter season in the Susitna River downstream of the dams."--Page 1-1.

This report describes a computer program, called ICECAL, developed by Darryl J. Calkins of Cold Regions Research and Engineering Laboratory, used for modeling instream ice. The program was used to model the Susitna River reach from the confluence at Talkeetna to Gold Creek. This reach includes many of the more important sloughs, and is expected to experience a greater change in winter regime than the lower river area in the event of dam construction. Data have been collected in this reach since 1980 and include the most complete data available on the river for ice modelling purposes.

Report of the winter 1983 Exploration Program to be used for the geotechnical design of the Watana Dam Project, part of the Susitna Hydroelectric Project in Alaska. Vol. 1, Main Report, summarizes the results of the exploration program; Vol. 2, Appendices, contains details of the geophysical exploration methods, drilling and sampling methods, bore hole logs and laboratory test results.

Results of the site investigation and laboratory testing program at the Watana Camp Site as they relate to the conceptual planning activities for the proposed airstrip.

The Terrestrial Program of Task 4, the Environmental Program for the Susitna Hydroelectric Project in Alaska, deals with wildlife and botanical resource issues. This report presents a detailed plan of study for 1984, involving field data collection, analysis, assessment and mitigation planning activities scheduled for this period.
