Weiss Lake, the most upstream lake on the Coosa, was constructed in 1961. The lake covers a massive 30,200 acres with 447 miles of shoreline. Weiss Lake is technically part of the Upper Coosa Basin (the Coosa Basin being divided into Upper, Middle and Lower sections). Coosa Riverkeeper maintains jurisdiction over the Middle and Lower Coosa Basins while our sister organization Upper Coosa Riverkeeper at Coosa River Basin Initiative maintains jurisdiction over the Upper Coosa Basin, including Weiss Lake. So, if you have questions about Weiss Lake or would like to file a pollution complaint in that area, please head over to the Coosa River Basin Initiative website.
