Youngs Lake Waupaca Co
Waupaca County, WisconsinMesotrophic
Youngs Lake Waupaca Co comes in at a B on the grading rubric — a respectable showing for a Wisconsin lake of its size and depth. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.
Mesotrophic conditions dominate at Youngs Lake Waupaca Co: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. Youngs Lake Waupaca Co reaches 15 ft at its deepest point — typical for Wisconsin mid-sized lakes, with seasonal stratification but limited cold-water refuge. The lake is compact at 3 acres, with partial shoreline records and little volume to buffer nutrient inputs. Youngs Lake Waupaca Co ranks 20 of 25 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.
