Round Lake Northeast Site
Chippewa County, WisconsinLimited DataMesotrophic
Round Lake Northeast Site earns an A — every scored parameter (phosphorus) rates among the best monitored waters in Chippewa County.
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. At 216 acres, Round Lake Northeast Site fits the Wisconsin median for monitored lakes, with partial shoreline records. Among the 15 graded lakes in Chippewa County, Round Lake Northeast Site ranks 2 — in the top quartile locally.
Round Lake Northeast Site has no invasive species recorded in Wisconsin state databases as of 2022, though prevention practices still apply at all access points. Walleye are documented at Round Lake Northeast Site, one of 5 fish species on record for the lake. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
