Flowage Lake FishingNRNot rated for water quality
Minnesota DNR surveys at Flowage Lake average 3.50 northern pike per unit of sampling effort (CPUE) across 1 survey. The most recent is a Standard Survey dated August 16, 1991. In St. Louis County, Minnesota, Flowage Lake has no letter grade — the only measurement available is water clarity, which is not a water-quality indicator on its own — EPA's National Lakes Assessment does not grade clarity. Water clarity averages 8.5 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 Flowage Lake
7 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 Flowage Lake
No stocking record for Flowage 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.
Survey results in full
Minnesota DNR surveys at Flowage Lake average 3.50 northern pike per unit of sampling effort (CPUE) across 1 survey. The most recent is a Standard Survey dated August 16, 1991.
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality does not assign an A–F grade on Flowage Lake — official chemistry is on file, not a letter, and the water-quality trend over 4 years of monitoring is stable. 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.
From the 1991-08-16 survey

NOP SIZE STRUCTURE IS GOOD WITH 64% OF THE FISH SAMPLED LONGER THAN 21 INCHES. NOP GROWTH RATES ARE FASTER THAN AREA MEAN, WITH FISH REACHING 21…

Common questions
What fish are in Flowage Lake?
Minnesota DNR surveys at Flowage Lake average 3.50 northern pike per unit of sampling effort (CPUE) across 1 survey. The most recent is a Standard Survey dated August 16, 1991. Minnesota DNR lists 7 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 Flowage Lake last surveyed?
The most recent fisheries survey on file for Flowage Lake is dated August 16, 1991. 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 Flowage Lake stocked?
No stocking record for Flowage 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 Flowage 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 Flowage Lake — official chemistry is on file, not a letter, and the water-quality trend over 4 years of monitoring is stable. 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.
