Triangle Lake FishingNRNot rated for water quality
Minnesota DNR surveys at Triangle Lake average 4.60 walleye per unit of sampling effort (CPUE) across 11 surveys. The most recent is a Standard Survey dated July 20, 2020. Length samples in the latest survey that recorded them ran 7–28 inches. In Lake County, Minnesota, Triangle Lake has no letter grade — no nutrient or algae measurement meets the evidence bar (at least 3 samples within 10 years). Water clarity averages 12.3 feet of visibility. 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.

From the 2020-07-20 survey
Triangle Lake is located 13 miles east of Ely. There are two "remote" public accesses. The most commonly used access is a 50 yard roller portage between the southern shore of Ojibway Lake and the northern shore of Triangle Lake. The portage is slightly uphill to Triangle but boats up to 16 feet long are able to be…

Common questions
What fish are in Triangle Lake?
Minnesota DNR surveys at Triangle Lake average 4.60 walleye per unit of sampling effort (CPUE) across 11 surveys. The most recent is a Standard Survey dated July 20, 2020. Length samples in the latest survey that recorded them ran 7–28 inches. Minnesota DNR lists 7 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 Triangle Lake last surveyed?
The most recent fisheries survey on file for Triangle Lake is dated July 20, 2020. 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 Triangle Lake stocked?
Minnesota DNR publishes a stocking history for Triangle 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 Triangle Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality does not assign an A–F grade on Triangle Lake — official chemistry is on file, not a letter. 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.
