Hart Lake FishingDWater-quality grade D
Minnesota DNR surveys at Hart Lake average 1.13 northern pike per unit of sampling effort (CPUE) across 1 survey. The most recent is a Standard Survey dated July 14, 1977. In Hubbard County, Minnesota, Hart Lake carries an overall water-quality grade of D. Water clarity averages 4.5 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.
Stocking at Hart Lake
No stocking record for Hart 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.

Common questions
What fish are in Hart Lake?
Minnesota DNR surveys at Hart Lake average 1.13 northern pike per unit of sampling effort (CPUE) across 1 survey. The most recent is a Standard Survey dated July 14, 1977. Those are survey results, not a catch report: a net set on one date measures what was in that net.
When was Hart Lake last surveyed?
The most recent fisheries survey on file for Hart Lake is dated July 14, 1977. 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 Hart Lake stocked?
No stocking record for Hart 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 Hart Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Hart Lake D from EPA Water Quality Portal chemistry, and the water-quality trend over 2 years of monitoring is declining. 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.
