Middle Spunk Lake FishingNRNot rated for water quality
Minnesota DNR surveys at Middle Spunk Lake average 12.13 largemouth bass per unit of sampling effort (CPUE) across 7 surveys. The most recent is a Standard Survey dated June 19, 2023. Length samples in the latest survey that recorded them ran 5–18 inches. In Stearns County, Minnesota, Middle Spunk Lake has no letter grade — the only measurement available is water clarity, which is not a water-quality indicator on its own — EPA's National Lakes Assessment does not grade clarity. Water clarity averages 12.0 feet of visibility, and there is one public boat landing. 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.

A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality does not assign an A–F grade on Middle Spunk Lake — official chemistry is on file, not a letter, and the water-quality trend over 6 years of monitoring is stable. Catch rate is not a swim clearance and is not a weekly bite report.

Top Species by Catch Rate
| Species | Avg catch rate (CPUE) | Avg Weight |
|---|---|---|

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 Middle Spunk Lake?
Minnesota DNR surveys at Middle Spunk Lake average 12.13 largemouth bass per unit of sampling effort (CPUE) across 7 surveys. The most recent is a Standard Survey dated June 19, 2023. Length samples in the latest survey that recorded them ran 5–18 inches. Minnesota DNR lists 17 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 Middle Spunk Lake last surveyed?
The most recent fisheries survey on file for Middle Spunk Lake is dated June 19, 2023. 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 Middle Spunk Lake stocked?
Minnesota DNR publishes a stocking history for Middle Spunk 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 Middle Spunk 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 Middle Spunk Lake — official chemistry is on file, not a letter, and the water-quality trend over 6 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.
