Lake Waramaug and its watershed in western Connecticut were sampled from March 1977 to March 1978 to develop information for a lake-management plan. Nutrient enrichment has degraded the lake water quality, resulting in increased algal population in recent years. Chemical analyses of surface-water inflow, ground-water inflow, and atmospheric deposition in the watershed indicate that surface-water inflow at the northeastern corner of the lake is the major source of nutrients discharged to the lake. Atmospheric deposition contains 0.01 to 0.47 milligrams per liter total phosphorus and 0.52 to 3.2 milligrams per liter total nitrogen. During the 7.3-month period of investigation, atmospheric deposition contributed 61,400 pounds of nitrogen and 3,150 pounds of phosphorus to the lake's watershed. Nutrient concentrations in ground water were relatively low, with total phosphorus ranging from 0.008 to 0.14 milligrams per liter.
