Nagawicka Lake vs Pewaukee Lake
Water quality, depth, fish species, and recreation comparison.
Nagawicka Lake reads lower on nutrients and algae than Pewaukee Lake. Both are in Waukesha County, Wisconsin.
Nagawicka Lake and Pewaukee Lake are both in Wisconsin — a same-state head-to-head where the comparison comes down to lake-specific differences in depth, watershed, and monitoring history rather than the broader state-level water-quality regime. The readings are close: Nagawicka Lake and Pewaukee Lake sit within a narrow band of each other on phosphorus, chlorophyll-a and clarity. The per-parameter table below shows where the small differences actually live.
With readings this close, the choice between the two lakes turns on non-water-quality factors: depth, fish species, public access, distance from home. The per-lake pages below cover all of those.
