Water quality and the effects of changes in phosphorus loading to Muskellunge Lake, Vilas County, Wisconsin
Dale M. Robertson, William J. Rose, David A. Saad
2003, Water-Resources Investigations Report 2003-4011
Muskellunge Lake is a productive, eutrophic lake because of high nutrient loading. Historical data indicate that water quality has only slightly degraded since the early 1970s, possibly because of phosphorus input from effluent from septic systems. A detailed phosphorus budget for the lake indicated that most of the phosphorus comes...
