Chippewa Flowage -Moore'S Bay Lake

Chippewa Flowage -Moore'S Bay Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

The lake sits in the mesotrophic zone — the band where most well-managed Wisconsin lakes fall. Chippewa Flowage -Moore'S Bay Lake is unusually deep for Wisconsin at 92 ft, which buffers the lake against summer warming and helps the deep water stay oxygenated. At 14,593 acres, Chippewa Flowage -Moore'S Bay Lake is one of the larger lakes in Sawyer County, with partial shoreline records supporting multiple distinct use patterns. Within the 52 graded lakes of Sawyer County, Chippewa Flowage -Moore'S Bay Lake sits at rank 47, near the bottom of the county list.

Eurasian watermilfoil is established at Chippewa Flowage -Moore'S Bay Lake, which can dampen recreational access and pressure the native plant community. The fishery includes walleye alongside the lake's other 8 documented species — a notable draw for Wisconsin anglers. Public access is available — the lake is on the Wisconsin DNR public-access list. Multiple sampling years from the Wisconsin DNR Citizen Lake Monitoring Network back the grade, so the letter should hold steady absent a major watershed shift.
