Survey results in full
Minnesota DNR's Targeted Survey on August 15, 2022 caught 0.53 walleye per gill net at Trout Lake.
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Trout Lake’s water-quality measurements separately, and the water-quality trend over 5 years of monitoring is improving. Catch rate is not a swim clearance and is not a weekly bite report.

From the 2022-08-15 survey
Trout Lake is located about 15 miles north of Grand Rapids in the Chippewa National Forest. Fish production is limited due to low fertility associated with oligotrophic conditions. Early records indicate Lake Trout were a large component of the fishery and has been a primary management species since 1975. Management…

Common questions
What fish are in Trout Lake?
Minnesota DNR's Targeted Survey on August 15, 2022 caught 0.53 walleye per gill net at Trout Lake. Minnesota DNR lists 9 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 Trout Lake last surveyed?
The most recent fisheries survey on file for Trout Lake is dated August 15, 2022. 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 Trout Lake stocked?
Minnesota DNR publishes a stocking history for Trout 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 Trout Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Trout Lake’s water-quality measurements separately, and the water-quality trend over 5 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
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.
