Description
In 1992, Water Sciences Branch began an intensive study of Thunder Lake to determine the cause of increasing algal growth and poor water quality. Of particular interest was a diversion to the lake from a tributary of the Paddle River, which was suspected of increasing the lake’s supply of phosphorus and nitrogen. The purpose of the monitoring program was to assess 1) changes in water quality in the lake, 2) the quantity of phosphorus and nitrogen in the diversion water compared with other nutrient sources, 3) what the lake would be like if the diversion is discontinued, 4) other ways to maintain water quality in Thunder Lake. This report highlights the results of this study.
