Why North Branch Kawishi Lake has no grade

We grade a lake only when the monitoring record supports a letter: at least three phosphorus or chlorophyll-a samples in the last ten years, scored against EPA National Lakes Assessment thresholds for this lake’s ecoregion. For North Branch Kawishi Lake, no nutrient or algae measurement meets the evidence bar (at least 3 samples within 10 years). Sampling here has recorded water clarity, phosphorus and algae (chlorophyll-a).

Not Rated is not an F. It is EPA Integrated Reporting Category 3 — insufficient information. The water here may be excellent or poor; nobody has measured enough of it to say. Everything below that has been measured is still reported on this page.

Sampling is run by MPCA and volunteer programs, and published through the EPA Water Quality Portal. Read the full grading methodology.

North Branch Kawishi Lake is a 182-acre lake in Lake County, Minnesota with a maximum depth of 13 feet. Overall water quality is declining over recent sampling years. The lake supports 7 documented fish species including bluegill, northern pike, and rock bass. No public access — the lake is private or restricted.

DNR fisheries survey

Minnesota DNR surveys at North Branch Kawishi Lake average 10.32 northern pike per unit of sampling effort (CPUE) across 5 surveys. The most recent is a Standard Survey dated July 14, 2023. Length samples in the latest survey that recorded them ran 21–30 inches.

A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality does not assign an A–F grade on North Branch Kawishi Lake — official chemistry is on file, not a letter, and the water-quality trend over 4 years of monitoring is declining. Catch rate is not a swim clearance and is not a weekly bite report.
