Gladstone Lake FishingAWater-quality grade A
Minnesota DNR surveys at Gladstone Lake average 20.16 largemouth bass per unit of sampling effort (CPUE) across 15 surveys. The most recent is a Standard Survey dated June 17, 2024. Length samples in the latest survey that recorded them ran 4–18 inches. In Crow Wing County, Minnesota, Gladstone Lake carries an overall water-quality grade of A. Water clarity averages 10.5 feet of visibility, and there is one public boat landing. 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 Gladstone Lake
15 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 Gladstone Lake
No stocking record for Gladstone 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.

A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Gladstone Lake A from EPA Water Quality Portal chemistry, and the water-quality trend over 6 years of monitoring is improving. Catch rate is not a swim clearance and is not a weekly bite report.

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.

Common questions
What fish are in Gladstone Lake?
Minnesota DNR surveys at Gladstone Lake average 20.16 largemouth bass per unit of sampling effort (CPUE) across 15 surveys. The most recent is a Standard Survey dated June 17, 2024. Length samples in the latest survey that recorded them ran 4–18 inches. Minnesota DNR lists 15 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 Gladstone Lake last surveyed?
The most recent fisheries survey on file for Gladstone Lake is dated June 17, 2024. 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 Gladstone Lake stocked?
No stocking record for Gladstone 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 Gladstone Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Gladstone Lake A from EPA Water Quality Portal chemistry, and the water-quality trend over 6 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
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.
