Potato Lake FishingNRNot rated for water quality
Minnesota DNR surveys at Potato Lake average 7.69 largemouth bass per unit of sampling effort (CPUE) across 12 surveys. The most recent is a Standard Survey dated July 11, 2022. Length samples in the latest survey that recorded them ran 5–18 inches. In Hubbard County, Minnesota, Potato Lake has no letter grade — no nutrient or algae measurement meets the evidence bar (at least 3 samples within 10 years). The lake has public access. 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.
Species recorded at Potato Lake
14 species on the Minnesota DNR list for this lake. A species on the list has been recorded here; it does not mean it is catchable today or in every part of the lake.
Stocking at Potato Lake
Minnesota DNR publishes a stocking history for this lake — which species went in, how many, and in which years. Read the years: a lake stocked in one year is not necessarily stocked in the next.

A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality does not assign an A–F grade on Potato Lake — official chemistry is on file, not a letter, 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.
DNR Fisheries Survey Summary
12 surveys on file from MN DNR Fisheries. Most recent: 2022-07-11 (Standard Survey).

CPUE = catch per unit effort, averaged across surveys (excludes juvenile shoreline seining). Higher CPUE means more abundant in standardized sampling. This is not a weekly bite report.

Common questions
What fish are in Potato Lake?
Minnesota DNR surveys at Potato Lake average 7.69 largemouth bass per unit of sampling effort (CPUE) across 12 surveys. The most recent is a Standard Survey dated July 11, 2022. Length samples in the latest survey that recorded them ran 5–18 inches. Minnesota DNR lists 14 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 Potato Lake last surveyed?
The most recent fisheries survey on file for Potato Lake is dated July 11, 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 Potato Lake stocked?
Minnesota DNR publishes a stocking history for Potato 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 Potato 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 Potato Lake — official chemistry is on file, not a letter, 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.
