6 Overlooked Largemouth Bass Lakes in Minnesota

Largemouth bass water that fishes above its reputation, picked from 2,339 surveyed Minnesota lakes by DNR catch rate, fish size and trophy record.

By · Published 2026-08-17

DNR surveys have recorded largemouth bass in 2,339 Minnesota lakes. Here are 6 of them.

Each card says what its lake is good for, because the lakes with the most largemouth bass and the lakes with the biggest largemouth bass are usually different lakes.

How these largemouth bass lakes were picked

Largemouth are counted by electrofishing: a shoreline run that stuns fish long enough to net and measure them, and the only gear the DNR publishes a largemouth band for. Its moderate mark is 50 largemouth bass per hour, cleared by every lake below. The quality length is 15 inches. These are survey numbers, not reports from the water.

Of the 2,339 lakes with largemouth bass on record, 1,204 clear the habitat gate: under 60 feet deep, with at least 50% of the water in the shallow zone where the food is. Anything already ranked among the state's best-known largemouth bass water is set aside, since those lakes are already well covered. These 6 are what is left after keeping only the lakes surveyed since 2016 that cleared the mark above, one entry per water body, each with a public boat launch. Full methodology: how the grades work.
