A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Wellner-Hageman Reservoir’s water-quality measurements separately, and the water-quality trend over 4 years of monitoring is declining. Catch rate is not a swim clearance and is not a weekly bite report.

Minnesota DNR lists 9 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 Wellner-Hageman Reservoir last surveyed?
The most recent fisheries survey on file for Wellner-Hageman Reservoir is dated July 25, 2022. 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 Wellner-Hageman Reservoir stocked?
Minnesota DNR publishes a stocking history for Wellner-Hageman Reservoir. 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.
Do the water-quality readings tell me how Wellner-Hageman Reservoir fishes?
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Wellner-Hageman Reservoir’s water-quality measurements separately, and the water-quality trend over 4 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
Water-quality readings are 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 with clear, low-nutrient water can still carry a meal limit on larger predator fish.
