Schwappauf Lake FishingDWater-quality grade D

In Hennepin County, Minnesota, Schwappauf Lake carries an overall water-quality grade of D. Water clarity averages 4.4 feet of visibility, and the lake has public access.

Survey results in full
Minnesota DNR surveys at Schwappauf Lake average 2.88 northern pike per unit of sampling effort (CPUE) across 3 surveys. The most recent is a Standard Survey dated August 4, 1992.
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Schwappauf Lake D from EPA Water Quality Portal chemistry, and the water-quality trend over 2 years of monitoring is stable. Catch rate is not a swim clearance and is not a weekly bite report.

From the 1992-08-04 survey
NUMBERS OF FISH CAPTURED WERE LOW DUE TO THE FISH KILL LAST WINTER. NOP WERE THE ONLY FISH CAPTURED IN THE GILLNETS, AND WERE SAMPLED IN NUMBERS NEAR THE STATE AND LOCAL MEDIANS FOR GILLNETS AND TRAPNETS. ONE NOP WAS AGE 0 (TWO FISH OF SIMILAR SIZE WERE GILLED IN TRAPNET LEADS), TWO AGE 3, ONE AGE 4, AND TWO AGE 5.…

Common questions
What fish are in Schwappauf Lake?
Minnesota DNR surveys at Schwappauf Lake average 2.88 northern pike per unit of sampling effort (CPUE) across 3 surveys. The most recent is a Standard Survey dated August 4, 1992. Those are survey results, not a catch report: a net set on one date measures what was in that net.
When was Schwappauf Lake last surveyed?
The most recent fisheries survey on file for Schwappauf Lake is dated August 4, 1992. 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 Schwappauf Lake stocked?
No stocking record for Schwappauf 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 Schwappauf Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Schwappauf Lake D from EPA Water Quality Portal chemistry, and the water-quality trend over 2 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.
