Species recorded at Birch Lake

No stocking record for Birch Lake appears in the Minnesota DNR material on file. That is an absence in the published record, not a confirmation that the lake is unstocked — some waters are managed as naturally reproducing and never appear in a stocking list at all.

Survey results in full
Minnesota DNR's Targeted Survey on August 11, 2025 caught 10.17 walleye per gill net at Birch Lake. Length samples in the latest survey that recorded them ran 4–28 inches.
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Birch Lake’s water-quality measurements separately, and the water-quality trend over 5 years of monitoring is declining. Catch rate is not a swim clearance and is not a weekly bite report.

Common questions
What fish are in Birch Lake?
Minnesota DNR's Targeted Survey on August 11, 2025 caught 10.17 walleye per gill net at Birch Lake. Length samples in the latest survey that recorded them ran 4–28 inches. Minnesota DNR lists 10 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 Birch Lake last surveyed?
The most recent fisheries survey on file for Birch Lake is dated August 11, 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 Birch Lake stocked?
No stocking record for Birch 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.
Do the water-quality readings tell me how Birch Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Birch Lake’s water-quality measurements separately, and the water-quality trend over 5 years of monitoring is declining. Catch rate is not a swim clearance and is not a weekly bite report.
Before you eat what you catch
Water-quality readings are 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 with clear, low-nutrient water can still carry a meal limit on larger predator fish.
