[2012]
As part of the Alaska Energy Authority's license application submitted to FERC for the proposed Susitna-Watana Hydroelectric Project, studies are needed on how construction and operation will affect flow and sediment transport, which will affect aquatic habitat and channel morphology downstream of the dam. This study plan outlines baseline information need to predict potential changes to flow and to sediment supply, transport, and capacity that will occur due to the Project.

Characterization of aquatic habitats in the Susitna River with potential to be affected by the Susitna-Watana Project.

2024-06-02T02:21:34Z

[2012]
Construction and operation of the Susitna-Watana Hydroelectric Project has the potential to alter aquatic habitats in the mainstem channel at tributary confluences as well as at the inlets and outlets to side channels, sloughs, and various off-channel habitat features both in the area of the inundation upstream from the Watana Dam site and downstream in the potential zone of project hydrologic influence. The goal of this study is to characterize habitats that will be altered and/or lost or gained from filling of the reservoir, hydropower operations, and associated changes in flow, water surface elevation, sediment regimes, and temperatures. The study area encompasses the entire Susitna River from the confluence with the Oshetna River to the area of tidal influence around River Mile 28.

Fish and aquatics instream flow study (Study 8.5), evaluation of relationships between fish abundance and specific microhabitat variables, technical memorandum

2014]
A study of existing aquatic habitats in the Susitna River watershed is being conducted as part of the planning of the Susitna-Watana Hydroelectric Project. The goal is to provide quantitative indices of existing aquatic habitats that enable a determination of the effects of alternative Project operational scenarios. FERC issued a Study Plan determination on April 1, 2013 to modify the study for additional analysis between fish abundance and microhabitat variables that had not bee planned previously. This memorandum addresses FERC's request, discusses the relevancy of eight microhabitat variables in the context of instream flow modeling, describes the data subset that is synoptic with fish presence or abundance measurements, and discusses results and recommendations on whether to include any variables in future habitat suitability criteria curve development.

Operations of the proposed Susitna-Watana Hydroelectric Project would likely affect the abundance and distribution of benthic algae and benthic macroinvertebrate populations, which could ultimately affect fish growth and productivity in the freshwater ecosystem. The chief goal of this study is to collect baseline data to assist in evaluating the potential Project-induced changes in flow and effects on environmental factors (e.g. temperature, substrate, water quality) and benthic macroinvertebrate and algal communities in the middle and lower Susitna River. This document describes research methods and sampling protocols.
