Two Island Lake

Two Island Lake earns an A — water clarity, phosphorus, and chlorophyll-a all rate among the best monitored waters in Chippewa County. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

Mesotrophic conditions dominate at Two Island Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. A maximum depth of 38 ft puts Two Island Lake in the middle of Wisconsin's depth distribution. At 29 acres, Two Island Lake sits below the Wisconsin median: a small water where shoreline activity has an outsized effect on water quality. Two Island Lake ranks 1 of 15 in Chippewa County, putting it in the upper tier of locally monitored lakes.

No invasive species are currently listed at Two Island Lake — the lake remains off the Wisconsin infested-waters roster. Bass fishing is part of the appeal: the species list runs to 2, anchored by largemouth and/or smallmouth bass. A documented public access point at Two Island Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. 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.
