Survey results in full
Minnesota DNR's Targeted Survey on August 17, 2020 caught 0.17 walleye per gill net at O'Reilly Lake.
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows O'Reilly Lake’s water-quality measurements separately, and the water-quality trend over 4 years of monitoring is declining. Catch rate is not a swim clearance and is not a weekly bite report.

From the 2020-08-17 survey
The 2012 lake management plan (LMP) indicated Largemouth Bass and Northern Pike were the primary management species while Black Crappie and Bluegill were secondary.

Common questions
What fish are in O'Reilly Lake?
Minnesota DNR's Targeted Survey on August 17, 2020 caught 0.17 walleye per gill net at O'Reilly Lake. Minnesota DNR lists 11 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 O'Reilly Lake last surveyed?
The most recent fisheries survey on file for O'Reilly Lake is dated August 17, 2020. 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 O'Reilly Lake stocked?
No stocking record for O'Reilly 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 O'Reilly Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows O'Reilly Lake’s water-quality measurements separately, and the water-quality trend over 4 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.
