Camelot Lake

Adams County, WisconsinMesotrophic

Camelot Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season. Clarity is the limiting factor — phosphorus is reasonable but suspended particles or algal cells keep water transparency below Wisconsin norms.

Mesotrophic conditions dominate at Camelot Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. Camelot Lake reaches 24 ft at its deepest point — typical for Wisconsin mid-sized lakes, with seasonal stratification but limited cold-water refuge. Camelot Lake covers 393 acres alongside partial shoreline records — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Among the 19 graded lakes in Adams County, Camelot Lake sits at rank 8, above the county median.

Zebra mussels have been documented at Camelot Lake, which alters the filter-feeding balance and can paradoxically increase water clarity while disrupting the food web. The fishery includes walleye among the lake's 4 documented species — a notable draw for Wisconsin anglers. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
