Lower Kaubashine Lake

Lower Kaubashine Lake earns an A — water clarity, phosphorus, and chlorophyll-a all rate among the best monitored waters in Oneida County. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

A TSI value of 39 puts Lower Kaubashine Lake in the oligotrophic range, where biological productivity stays low and the water column remains clear. The lake bottoms out at 36 ft — a moderate depth that supports a warm-water fishery without the year-round cold refuge a deeper basin provides. Lower Kaubashine Lake covers 198 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 134 graded lakes in Oneida County, Lower Kaubashine Lake ranks 26 — in the top quartile locally.

An invasive species record — Purple Loosestrife — has been logged at Lower Kaubashine Lake; Wisconsin DNR maintains the official infested-waters list. The fishery includes walleye alongside the lake's other 6 documented species — a notable draw for Wisconsin anglers. 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.
