A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Tamarack Bay Lake C 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.

When was Tamarack Bay Lake last surveyed?
The most recent fisheries survey on file for Tamarack Bay Lake is dated May 16, 2024. 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 Tamarack Bay Lake stocked?
Minnesota DNR publishes a stocking history for Tamarack Bay 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 Tamarack Bay Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Tamarack Bay Lake C 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.
