Water Quality Task Force
Our task force activities include collecting samples of Hamlin Lake water for analysis. Water samples as well as stream and tributary flow data are collected to determine nutrient and sediment loading to the lake (Pounds per Day). Sample points are also selected in the upper and lower lakes for additional Total Phosphorus analysis. This data is valuable to us for identifying potential “hot spots” in the lake.
