Abstract
An adjusted water budget prepared for Pine Lake, a candidate for lake-quality restoration, indicates that of approximately 790 acre-feet of water that enters the lake in a typical year, 410 acre-feet is from precipitation, 350 acre-feet is from surface inflow, and 30 acre-feet is from ground-water seepage. A nearly equal amount of water leaves the lake and of this, 130 acre-feet is by evaporation, 659 acre-feet is by surface runoff, and less than one acre-foot is by ground-water seepage. Based on these amounts of inflow and outflow, the theoretical water-renewal time of the lake is calculated to be 2.2 years. The contributions of inorganic nitrogen and phosphorus to the lake in a typical year from precipitation, surface inflow, and ground-water inflow is about 2,500 pounds of nitrogen and 49 pounds of phosphorus.
