Big Pine Lake FishingCWater-quality grade C
Minnesota DNR surveys at Big Pine Lake average 17.99 walleye per unit of sampling effort (CPUE) across 15 surveys. The most recent is a Targeted Survey dated June 2, 2025. Length samples in the latest survey that recorded them ran 7–26 inches. In Otter Tail County, Minnesota, Big Pine Lake carries an overall water-quality grade of C. Water clarity averages 8.7 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.

A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Big Pine Lake C 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.

Common questions
What fish are in Big Pine Lake?
Minnesota DNR surveys at Big Pine Lake average 17.99 walleye per unit of sampling effort (CPUE) across 15 surveys. The most recent is a Targeted Survey dated June 2, 2025. Length samples in the latest survey that recorded them ran 7–26 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 Big Pine Lake last surveyed?
The most recent fisheries survey on file for Big Pine Lake is dated June 2, 2025. 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 Big Pine Lake stocked?
No stocking record for Big Pine Lake appears in the Minnesota DNR material on file. That is not the same as a confirmed unstocked lake: it means no stocking document was published for it in the records this page draws on.
Does the water-quality grade tell me how Big Pine Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Big Pine Lake C 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.
