American Eel Lakes in Minnesota

Rough fish like American Eel are often associated with eutrophic, nutrient-loaded waters. Their presence — documented in 5 Minnesota lakes — is often a signal of how the rest of the fishery is functioning. American Eel is narrowly distributed — only 4 lakes in Minnesota and 1 in Michigan have a documented record. The constraint is usually habitat: cold water, specific depth profile, or river connection.

Rough-fish-dominant lakes are worth checking the grade on: a rough-fish-heavy fishery often reflects an underlying nutrient-loading problem in the watershed. Cross-reference the American Eel lake list below against the letter grades: lakes with both an A or B grade and American Eel documented are the best places to start for recreational targeting.
