Dean Lake FishingFWater-quality grade F
Minnesota DNR surveys at Dean Lake average 14.07 largemouth bass per unit of sampling effort (CPUE) across 6 surveys. The most recent is a Standard Survey dated July 29, 2019. Length samples in the latest survey that recorded them ran 6–20 inches. In Wright County, Minnesota, Dean Lake carries an overall water-quality grade of F. Water clarity averages 4.3 feet of visibility, and there is one public boat landing. The survey figures on this page are Minnesota DNR's own; the water-quality grade comes from EPA Water Quality Portal samples. Neither is a forecast of today's bite.

Common questions
What fish are in Dean Lake?
Minnesota DNR surveys at Dean Lake average 14.07 largemouth bass per unit of sampling effort (CPUE) across 6 surveys. The most recent is a Standard Survey dated July 29, 2019. Length samples in the latest survey that recorded them ran 6–20 inches. Minnesota DNR lists 12 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 Dean Lake last surveyed?
The most recent fisheries survey on file for Dean Lake is dated July 29, 2019. 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 Dean Lake stocked?
Minnesota DNR publishes a stocking history for Dean Lake. 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 Dean Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Dean Lake F from EPA Water Quality Portal chemistry, and the water-quality trend over 6 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.
