Charlotte Lake

Charlotte Lake earns an A — water clarity, phosphorus, and chlorophyll-a all rate among the best monitored waters in Wright County. Sub-grades cluster within a single letter of each other, which usually means the lake is in stable trophic balance rather than fighting one specific stressor.

A TSI value of 38 puts Charlotte Lake in the oligotrophic range, where biological productivity stays low and the water column remains clear. A maximum depth of 46 ft puts Charlotte Lake in the middle of Minnesota's depth distribution. Charlotte Lake covers 253 acres alongside 3.9 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Charlotte Lake ranks 3 of 64 in Wright County, putting it in the upper tier of locally monitored lakes.

Charlotte Lake 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 10, anchored by largemouth and/or smallmouth bass. A documented public access point at Charlotte Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. Ice-out has been recorded 15 times at Charlotte Lake, with a median around Apr 7. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
