Round Lake FishingBWater-quality grade B
Minnesota DNR surveys at Round Lake average 9.13 northern pike per unit of sampling effort (CPUE) across 5 surveys. The most recent is a Standard Survey dated June 16, 2010. Length samples in the latest survey that recorded them ran 11–31 inches. In Otter Tail County, Minnesota, Round Lake carries an overall water-quality grade of B. Water clarity averages 7.9 feet of visibility, and there is one public boat landing. The survey figures on this page are Minnesota DNR's own; the water-quality grade comes from EPA Water Quality Portal samples. Neither is a forecast of today's bite.
Species recorded at Round Lake
13 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.

Top Species by Catch Rate
| Species | Avg catch rate (CPUE) | Avg Weight |
|---|---|---|

CPUE = catch per unit effort, averaged across surveys (excludes juvenile shoreline seining). Higher CPUE means more abundant in standardized sampling. This is not a weekly bite report.

Common questions
What fish are in Round Lake?
Minnesota DNR surveys at Round Lake average 9.13 northern pike per unit of sampling effort (CPUE) across 5 surveys. The most recent is a Standard Survey dated June 16, 2010. Length samples in the latest survey that recorded them ran 11–31 inches. Minnesota DNR lists 13 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 June 16, 2010. 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.
Does the water-quality grade tell me how Round Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Round Lake B 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.
