Halfbreed Lake FishingAWater-quality grade A
Minnesota DNR surveys at Halfbreed Lake average 3.73 northern pike per unit of sampling effort (CPUE) across 4 surveys. The most recent is a Standard Survey dated July 29, 1997. Length samples in the latest survey that recorded them ran 11–27 inches. In Washington County, Minnesota, Halfbreed Lake carries an overall water-quality grade of A. Water clarity averages 5.2 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 Halfbreed Lake
10 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 Halfbreed Lake
No stocking record for Halfbreed 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 Halfbreed Lake A from EPA Water Quality Portal chemistry, and the water-quality trend over 2 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.

From the 1997-07-29 survey
Sunfish species (bluegill, pumpkinseed, green, and hybrid sunfish) dominated the fish population. Only 34 (6.9%) of the fish were over 6 inches in length with 7 (1.7%) over 7 inches long. Black crappie were present in very low numbers. Northern pike were the most abundant predator, with most fish between 22 and 28…

Common questions
What fish are in Halfbreed Lake?
Minnesota DNR surveys at Halfbreed Lake average 3.73 northern pike per unit of sampling effort (CPUE) across 4 surveys. The most recent is a Standard Survey dated July 29, 1997. Length samples in the latest survey that recorded them ran 11–27 inches. Minnesota DNR lists 10 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 Halfbreed Lake last surveyed?
The most recent fisheries survey on file for Halfbreed Lake is dated July 29, 1997. 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 Halfbreed Lake stocked?
No stocking record for Halfbreed 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 Halfbreed Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Halfbreed Lake A from EPA Water Quality Portal chemistry, and the water-quality trend over 2 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.
