On 29 July 2008 a sediment core were taken in Granite Lake using a gravity corer. Granite Lake has experienced a moderate increase in nutrients which has resulted in a decline in water clarity as algal growth has increased. In addition to the increased nutrients, there appear to be more submerged aquatic plants at the present time. These changes are common in lakes like Granite Lake that have shoreline development as well as some agriculture in their watershed.

The Granite Lake Association is sponsoring a 1-year small-scale planning grant to generally appraise water quality conditions in the lake. This project will collect water quality data from an additional surface water location designated by the Citizen Lake Monitoring Network, and at two stream sites, one above the lake inlet and one below the lake outlet. Water samples will be analyzed for a suite of inorganic water quality parameters by the Wisconsin State Lab of Hygiene. In addition, a one time top/bottom paleolimnological core will be collected and evaluated. Watershed analysis data provided by Barron County will be evaluated to determine areas of concern within the watershed.
