Tiger Cat Flowage Lake

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

The lake sits in the mesotrophic zone — the band where most well-managed Wisconsin lakes fall. The lake bottoms out at 30 ft — a moderate depth that supports a warm-water fishery without the year-round cold refuge a deeper basin provides. The lake's 819 acres and partial shoreline records put it in the mid-range bucket — large enough for varied use, small enough that watershed inputs reach the whole basin. Tiger Cat Flowage Lake ranks 16 of 50 in Sawyer County — solidly in the upper half of the local distribution.

Eurasian watermilfoil has been documented at Tiger Cat Flowage Lake, requiring shoreline management to keep dense mats from crowding native vegetation. Walleye are documented at Tiger Cat Flowage Lake, one of 4 fish species on record for the lake. Public access is available — the lake is on the Wisconsin DNR public-access list. 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.
