Sea Gull Lake FishingAWater-quality grade A
Minnesota DNR surveys at Sea Gull Lake average 2.55 smallmouth bass per unit of sampling effort (CPUE) across 5 surveys. The most recent is a Standard Survey dated August 14, 2017. Length samples in the latest survey that recorded them ran 1–17 inches. In Cook County, Minnesota, Sea Gull Lake carries an overall water-quality grade of A. Water clarity averages 14.3 feet of visibility, and the lake has public access. 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 Sea Gull Lake
12 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 Sea Gull Lake
No stocking record for Sea Gull 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.

Top Species by Catch Rate
| Species | Avg catch rate (CPUE) | Avg Weight |

| Walleye | 1.49 | 0.93 lb |
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 2017-08-14 survey
Gull Lake lies on the Sea Gull River between Sea Gull Lake (upstream) and Saganaga Lake (downstream), and was last surveyed in 1998. Movement of fish between Saganaga and Gull Lakes occurs regularly, while a barrier falls blocks movement of fish (and other organisms) from Gull Lake to Sea Gull Lake. This standard…

Common questions
What fish are in Sea Gull Lake?
Minnesota DNR surveys at Sea Gull Lake average 2.55 smallmouth bass per unit of sampling effort (CPUE) across 5 surveys. The most recent is a Standard Survey dated August 14, 2017. Length samples in the latest survey that recorded them ran 1–17 inches. Minnesota DNR lists 12 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 Sea Gull Lake last surveyed?
The most recent fisheries survey on file for Sea Gull Lake is dated August 14, 2017. 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 Sea Gull Lake stocked?
No stocking record for Sea Gull 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.
Does the water-quality grade tell me how Sea Gull Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Sea 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.
