| Abstract: | A dam constructed at the outlet of Bradley Lake near Homer, Alaska has blocked natural flows to the lower Bradley River. To protect salmon egg incubation habitat during the period November 2 to April 30, a fish-water bypass was incorporated into the design of the dam to ensure a minimum discharge of 40 cubic feet per second in the lower river. This minimum flow determination was based on an open-water instream flow study that did not take into account effects of ice formation. A study was begun in March 1993 to determine winter flow conditions in the lower Bradley River. As a part of this study, data were collected at sites in the lower Bradley River to measure discharge, wetted perimeter, cross-sectional area, water depth, flow velocity, and specific conductance, as well as temperature and dissolved oxygen from both surface water and intragravel water. Discharge and specific conduc- tance in the Middle Fork Bradley River below North Fork Bradley River were also measured. This report presents data collected between March 1993 and April 1994. |
