Youngs Lake Waupaca Co
Waupaca County, WisconsinOligotrophic
On the LakeGrade rubric, Youngs Lake Waupaca Co pulls an A: clarity at 33.6 ft and 22 µg/L of phosphorus put it in the top bracket for Wisconsin. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.
A TSI value of 38 puts Youngs Lake Waupaca Co in the oligotrophic range, where biological productivity stays low and the water column remains clear. The lake's maximum depth is not yet documented in state morphometric records — context for its physical structure remains limited. The lake is compact at 3 acres, with partial shoreline records and little volume to buffer nutrient inputs. Youngs Lake Waupaca Co ranks 26 of 27 in Waupaca County — at the lower end of the locally monitored distribution.
Youngs Lake Waupaca Co carries an invasive watermilfoil record — boat-launch decontamination and shoreline care matter more here than at uninfested lakes. Walleye are documented at Youngs Lake Waupaca Co, one of 5 fish species on record for the lake. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
