Common questions
What fish are in Spring Lake?
Minnesota DNR's Standard Survey on August 11, 1971 caught 0.20 walleye per gill net at Spring Lake. Those are survey results, not a catch report: a net set on one date measures what was in that net.
When was Spring Lake last surveyed?
The most recent fisheries survey on file for Spring Lake is dated August 11, 1971. 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 Spring Lake stocked?
No stocking record for Spring 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 Spring Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Spring Lake’s water-quality measurements separately. Catch rate is not a swim clearance and is not a weekly bite report.
