Lake Lime
Portage County, WisconsinLimited DataMesotrophic
Lake Lime carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.
Mesotrophic conditions dominate at Lake Lime: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. Lake Lime reaches 29 ft at its deepest point — typical for Wisconsin mid-sized lakes, with seasonal stratification but limited cold-water refuge. Lake Lime is small — 45 acres alongside partial shoreline records — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. Lake Lime ranks 14 of 28 in Portage County — solidly in the upper half of the local distribution.
Lake Lime carries an invasive watermilfoil record — boat-launch decontamination and shoreline care matter more here than at uninfested lakes. Bass fishing is part of the appeal: the species list runs to 3, anchored by largemouth and/or smallmouth bass. Public access is available — the lake is on the Wisconsin DNR public-access list. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
