Species recorded at Round Lake
15 species on the Minnesota DNR list for this lake. A species on the list has been recorded here; it does not mean it is catchable today or in every part of the lake.
Stocking at Round Lake
Minnesota DNR publishes a stocking history for this lake — which species went in, how many, and in which years. Read the years: a lake stocked in one year is not necessarily stocked in the next.

Survey results in full
Minnesota DNR's Targeted Survey on July 21, 2025 caught 0.42 walleye per trap net at Round Lake. Length samples in the latest survey that recorded them ran 4–22 inches.
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Round Lake’s water-quality measurements separately, and the water-quality trend over 6 years of monitoring is declining. Catch rate is not a swim clearance and is not a weekly bite report.

From the 2025-09-09 survey
Fall night electrofishing was conducted on 9/9/2025. Night electrofishing in the fall is a common method used to monitor the abundance of young-of-the-year (YOY) and yearling (age 1) Walleye. This survey is intended to provide information on Walleye survival and recruitment (both natural and from fry stocking) and…

Common questions
What fish are in Round Lake?
Minnesota DNR's Targeted Survey on July 21, 2025 caught 0.42 walleye per trap net at Round Lake. Length samples in the latest survey that recorded them ran 4–22 inches. Minnesota DNR lists 15 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 Round Lake last surveyed?
The most recent fisheries survey on file for Round Lake is dated September 9, 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 Round Lake stocked?
Minnesota DNR publishes a stocking history for Round Lake. It records which species were released, in what numbers and in which years — the source documents are linked further down this page. A lake can be stocked in some years and not others, so read the years rather than assuming an annual release.
Do the water-quality readings tell me how Round Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Round Lake’s water-quality measurements separately, and the water-quality trend over 6 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.
