Stocking at Clearwater Lake
No stocking record for Clearwater Lake appears in the Minnesota DNR material on file. That is an absence in the published record, not a confirmation that the lake is unstocked — some waters are managed as naturally reproducing and never appear in a stocking list at all.
Survey results in full
Minnesota DNR's Standard Survey on July 17, 2000 caught 2.67 walleye per gill net at Clearwater Lake. Length samples in the latest survey that recorded them ran 7–22 inches.
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Clearwater Lake’s water-quality measurements separately, and the water-quality trend over 6 years of monitoring is stable. Catch rate is not a swim clearance and is not a weekly bite report.

From the 2025-08-13 survey
Temperature and dissolved oxygen (DO) measurements were collected from the deepest basin in Caribou Lake on August 13th, 2025, to evaluate the quantity and quality of cold, oxygenated water (i.e., oxythermal habitat) available to Lake Whitefish, the only coldwater species present in this lake. During the summer, Lake…

Common questions
What fish are in Clearwater Lake?
Minnesota DNR's Standard Survey on July 17, 2000 caught 2.67 walleye per gill net at Clearwater Lake. Length samples in the latest survey that recorded them ran 7–22 inches. Those are survey results, not a catch report: a net set on one date measures what was in that net.
When was Clearwater Lake last surveyed?
The most recent fisheries survey on file for Clearwater Lake is dated August 13, 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 Clearwater Lake stocked?
No stocking record for Clearwater 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 Clearwater Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Clearwater Lake’s water-quality measurements separately, and the water-quality trend over 6 years of monitoring is stable. 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.
