Round Lake Northeast Site
Chippewa County, WisconsinLimited DataMesotrophic
Round Lake Northeast Site earns an A — water clarity, phosphorus, and chlorophyll-a all rate among the best monitored waters in Chippewa 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.
Mesotrophic conditions dominate at Round Lake Northeast Site: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. The lake bottoms out at 18 ft — a moderate depth that supports a warm-water fishery without the year-round cold refuge a deeper basin provides. Round Lake Northeast Site covers 216 acres alongside partial shoreline records — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Round Lake Northeast Site ranks 8 of 16 in Chippewa County — solidly in the upper half of the local distribution.
No invasive species are currently listed at Round Lake Northeast Site — the lake remains off the Wisconsin infested-waters roster. The fishery includes walleye alongside the lake's other 5 documented species — a notable draw for Wisconsin anglers. Public access is available — the lake is on the Wisconsin DNR public-access list. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
