Description
Summary:A baseline water quality study was started in 2012 and continued through the winter 2013/2014 winter season to document historical water quality in order to assess the effects of the proposed Susitna-Watana Hydroelectric Project on water quality in the Susitna River basin. The study area includes the Susitna River starting at river mile 19.9 (for water temperature monitoring) and 29.9 (for other water quality monitoring) to river mile 235.2 (Oshetna River) and selected tributaries within the proposed transmission lines and access corridors. Data collected in the 1970s and 1980s were evaluated in this study. Meteorological data were collected at various stations. The study included surface water physical, chemical, and bacterial conditions; metals concentrations in sediment and fish tissues; and a pilot Thermal Infrared Remote (TIR) sensing effort to obtain data to map the groundwater discharge and possible extent of thermal refugia. This study is in progress, and the data will be used in the Water Quality Modeling Study to predict Project effects under alternative Project operations. This document details Alaska Energy Authority's status in implementing the study as set forth in the FERC-approved Revised study plan and as modified by FERC's April 1 Study Plan Determination and by the Quality Assurance Project Plan.
