Missouri Lake FishingNRNot rated for water quality
Minnesota DNR surveys at Missouri Lake average 7.25 northern pike per unit of sampling effort (CPUE) across 6 surveys. The most recent is a Standard Survey dated June 8, 2017. Length samples in the latest survey that recorded them ran 11–30 inches. In Cook County, Minnesota, Missouri Lake has no letter grade — no nutrient or algae measurement meets the evidence bar (at least 3 samples within 10 years). Water clarity averages 4.1 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 Missouri Lake
1 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 Missouri Lake
No stocking record for Missouri 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 does not assign an A–F grade on Missouri Lake — official chemistry is on file, not a letter. Catch rate is not a swim clearance and is not a weekly bite report.
DNR Fisheries Survey Summary
6 surveys on file from MN DNR Fisheries. Most recent: 2017-06-08 (Standard Survey).
Top Species by Catch Rate
| Species | Avg catch rate (CPUE) | Avg Weight |
|---|---|---|

| White Sucker | 6.83 | 0.93 lb |
| Brook Trout | 1.25 | 0.44 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 2017-06-08 survey
Missouri Lake is a small, very shallow water connected to the Poplar River (a desginated trout stream) by its outlet, Missouri Creek. As late as 1995 it supported a small number of naturally-produced Brook Trout, and fairly high numbers of White Sucker. By 1999 Northern Pike had become established in the lake. Since…

Common questions
What fish are in Missouri Lake?
Minnesota DNR surveys at Missouri Lake average 7.25 northern pike per unit of sampling effort (CPUE) across 6 surveys. The most recent is a Standard Survey dated June 8, 2017. Length samples in the latest survey that recorded them ran 11–30 inches. Minnesota DNR lists 1 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 Missouri Lake last surveyed?
The most recent fisheries survey on file for Missouri Lake is dated June 8, 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 Missouri Lake stocked?
No stocking record for Missouri 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 Missouri Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality does not assign an A–F grade on Missouri Lake — official chemistry is on file, not a letter. 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.
