In Cass County, Minnesota, Gull Lake carries an overall water-quality grade of A. Water clarity averages 15.0 feet of visibility, and there are 3 public boat landings.

From the 2025-09-23 survey
Gull Lake is normally stocked annually with Walleye fry at the rate of 1,000 per littoral acre (2,825,000 fry). Fingerlings are stocked on a contingency basis if fall electrofishing results are less than 30 young-of-the-year (YOY) Walleye per hour for two consecutive years; fingerlings were last stocked in the fall of…

Common questions
What fish are in Gull Lake?
Minnesota DNR's Standard Survey on July 14, 2025 caught 5.67 walleye per gill net at Gull Lake. Length samples in the latest survey that recorded them ran 4–20 inches. Minnesota DNR lists 22 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 Gull Lake last surveyed?
The most recent fisheries survey on file for Gull Lake is dated September 23, 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 Gull Lake stocked?
Minnesota DNR publishes a stocking history for Gull 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 Gull Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Gull Lake A from EPA Water Quality Portal chemistry. 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.
