Hattie Lake FishingNRNot rated for water quality
Minnesota DNR surveys at Hattie Lake average 7.19 walleye per unit of sampling effort (CPUE) across 12 surveys. The most recent is a Targeted Survey dated May 3, 2023. Length samples in the latest survey that recorded them ran 9–25 inches. In Stevens County, Minnesota, Hattie 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 3.5 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 Hattie 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 Hattie Lake

A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality does not assign an A–F grade on Hattie Lake — official chemistry is on file, not a letter, and the water-quality trend over 3 years of monitoring is improving. Catch rate is not a swim clearance and is not a weekly bite report.

Top Species by Catch Rate
| Species | Avg catch rate (CPUE) | Avg Weight |
|---|---|---|
| Black Bullhead | 103.73 | 0.33 lb |
| Fathead Minnow | 55.67 | — |
| Yellow Perch | 12.59 | 0.31 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 2023-05-03 survey
This targeted survey was completed to determine extent of winterkill following the severe 2022-2023 winter. Despite winter operation of an aeration system, trap netting results suggested winterkill severity was high. It is worth noting that low oxygen levels were already being observed in late December, prior to the…

Common questions
What fish are in Hattie Lake?
Minnesota DNR surveys at Hattie Lake average 7.19 walleye per unit of sampling effort (CPUE) across 12 surveys. The most recent is a Targeted Survey dated May 3, 2023. Length samples in the latest survey that recorded them ran 9–25 inches. 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 Hattie Lake last surveyed?
The most recent fisheries survey on file for Hattie Lake is dated May 3, 2023. 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 Hattie Lake stocked?
Minnesota DNR publishes a stocking history for Hattie 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 Hattie 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 Hattie Lake — official chemistry is on file, not a letter, and the water-quality trend over 3 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.
