Schoenick Lake at
Shawano County, WisconsinMesotrophic
Schoenick Lake at carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season. Phosphorus is the parameter holding the grade back — runoff from the surrounding watershed appears to keep nutrient levels elevated through the summer.
Mesotrophic conditions dominate at Schoenick Lake at: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. The lake bottoms out at 34 ft — a moderate depth that supports a warm-water fishery without the year-round cold refuge a deeper basin provides. At 42 acres, Schoenick Lake at sits below the Wisconsin median: a small water where shoreline activity has an outsized effect on water quality. Schoenick Lake at ranks 21 of 27 in Shawano County — at the lower end of the locally monitored distribution.
Eurasian watermilfoil has been documented at Schoenick Lake at, requiring shoreline management to keep dense mats from crowding native vegetation. Bass fishing is part of the appeal: the species list runs to 3, anchored by largemouth and/or smallmouth bass. Monitoring depth is thin here: the LakeGrade rubric is applied to a small number of sample years, and the grade will be revised as more data accumulates.
