Species recorded at Wolf Lake
18 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 Wolf 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.

1 public boat landing is recorded on Wolf Lake. Minnesota DNR lists the public access sites, including ramp type and parking, in the documents below.
Survey results in full
Minnesota DNR's Targeted Survey on July 10, 2019 caught 6.25 largemouth bass per hour of electrofishing at Wolf Lake.
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Wolf Lake’s water-quality measurements separately, and the water-quality trend over 4 years of monitoring is improving. Catch rate is not a swim clearance and is not a weekly bite report.

From the 2025-08-07 survey
Temperature and dissolved oxygen measurements were collected from the deepest basin in Wolf Lake, which is located partially within the Leech Lake Reservation, on August 7th, 2025, to evaluate the quantity and quality of cold, oxygenated water (oxythermal habitat) available to coldwater fish species such as Cisco,…

Common questions
What fish are in Wolf Lake?
Minnesota DNR's Targeted Survey on July 10, 2019 caught 6.25 largemouth bass per hour of electrofishing at Wolf Lake. Minnesota DNR lists 18 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 Wolf Lake last surveyed?
The most recent fisheries survey on file for Wolf Lake is dated August 7, 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 Wolf Lake stocked?
Minnesota DNR publishes a stocking history for Wolf 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 Wolf Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Wolf Lake’s water-quality measurements separately, and the water-quality trend over 4 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.
