In Otter Tail County, Minnesota, Iverson Lake has no letter grade — no nutrient or algae measurement meets the evidence bar (at least 3 samples within 10 years).

Neither is a forecast of today's bite.

From the 1985-06-12 survey
Bluegill catch per trap net lift increased from 34.3 per net in the 1982 survey to 690.0 per net. Average weight per bluegill decreased from 0.22 lb. in 1982 to .09 lb. Walleye fry stocking has been very successful. The 1981 and 1983 year classes were well represented in the sample. Average weight of walleye was just…

Common questions
What fish are in Iverson Lake?
Minnesota DNR surveys at Iverson Lake average 3.00 walleye per unit of sampling effort (CPUE) across 1 survey. The most recent is a Standard Survey dated June 12, 1985. Minnesota DNR lists 6 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 Iverson Lake last surveyed?
The most recent fisheries survey on file for Iverson Lake is dated June 12, 1985. 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 Iverson Lake stocked?
Minnesota DNR publishes a stocking history for Iverson 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 Iverson 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 Iverson 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.
