Survey results in full
Minnesota DNR surveys at Round Island Lake average 0.25 walleye per unit of sampling effort (CPUE) across 1 survey. The most recent is a Standard Survey dated June 27, 1983.
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Round Island 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 Round Island Lake?
Minnesota DNR surveys at Round Island Lake average 0.25 walleye per unit of sampling effort (CPUE) across 1 survey. The most recent is a Standard Survey dated June 27, 1983. Those are survey results, not a catch report: a net set on one date measures what was in that net.
When was Round Island Lake last surveyed?
The most recent fisheries survey on file for Round Island Lake is dated June 27, 1983. 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 Round Island Lake stocked?
No stocking record for Round Island 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 Round Island Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Round Island 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.
