A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade.

Common questions
What fish are in Lake Winnibigoshish?
Minnesota DNR surveys at Lake Winnibigoshish average 20.75 walleye per unit of sampling effort (CPUE) across 38 surveys. The most recent is a Standard Survey dated May 16, 2024. Length samples in the latest survey that recorded them ran 3–24 inches. Minnesota DNR lists 20 species for the lake in total. Those are survey results, not a catch report: a net set on one date measures what was in that net.
When was Lake Winnibigoshish last surveyed?
The most recent fisheries survey on file for Lake Winnibigoshish is dated May 16, 2024. Survey intervals vary by lake and by species; a gap of several years between surveys is normal and does not mean the record is missing.
Is Lake Winnibigoshish stocked?
Minnesota DNR publishes a stocking history for Lake Winnibigoshish. It records which species were released, in what numbers and in which years — the source documents are linked further down this page. A lake can be stocked in some years and not others, so read the years rather than assuming an annual release.
Does the water-quality grade tell me how Lake Winnibigoshish fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Lake Winnibigoshish C from EPA Water Quality Portal chemistry, and the water-quality trend over 2 years of monitoring is improving. Catch rate is not a swim clearance and is not a weekly bite report.
Before you eat what you catch
A water-quality grade is not a consumption advisory. Mercury and PCB advice for Minnesota waters comes from MDH, and it is issued per species and per size class — a lake can grade well and still carry a meal limit on larger predator fish.
