Clear Lake FishingAWater-quality grade A
Minnesota DNR surveys at Clear Lake average 30.57 bluegill per unit of sampling effort (CPUE) across 19 surveys. The most recent is a Targeted Survey dated July 28, 2025. Length samples in the latest survey that recorded them ran 3–8 inches. In Aitkin County, Minnesota, Clear Lake carries an overall water-quality grade of A. Water clarity averages 15.0 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 Clear Lake
14 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 Clear 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 surveys at Clear Lake average 30.57 bluegill per unit of sampling effort (CPUE) across 19 surveys. The most recent is a Targeted Survey dated July 28, 2025. Length samples in the latest survey that recorded them ran 3–8 inches.
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Clear Lake A from EPA Water Quality Portal chemistry, 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.
DNR Fisheries Survey Summary
19 surveys on file from MN DNR Fisheries. Most recent: 2025-07-28 (Targeted Survey).
Top Species by Catch Rate
| Species | Avg catch rate (CPUE) | Avg Weight |
|---|---|---|
| Bluntnose Minnow | 39.69 | — |
| Bluegill | 30.57 | 0.18 lb |
| Yellow Bass | 14.69 | 0.37 lb |
| Spottail Shiner | 8.16 | — |
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.

From the 2025-07-28 survey
A targeted survey of nearshore fish species in Clear Lake was conducted on July 28-30, 2025, by Lake Biological Monitoring and Assessment (LBMA) program staff. Sampling sites were evenly spaced around the lake, and each was sampled by backpack electrofishing and seining with a 50-foot or 15-foot seine, where possible.…

Common questions
What fish are in Clear Lake?
Minnesota DNR surveys at Clear Lake average 30.57 bluegill per unit of sampling effort (CPUE) across 19 surveys. The most recent is a Targeted Survey dated July 28, 2025. Length samples in the latest survey that recorded them ran 3–8 inches. Minnesota DNR lists 14 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 Clear Lake last surveyed?
The most recent fisheries survey on file for Clear Lake is dated July 28, 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 Clear Lake stocked?
Minnesota DNR publishes a stocking history for Clear 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 Clear Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Clear Lake A from EPA Water Quality Portal chemistry, 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
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.
