American Eel Lakes in Minnesota

Rough fish like American Eel are often associated with eutrophic, nutrient-loaded waters. Their presence — documented in 4 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 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 phosphorus and chlorophyll-a readings 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 each lake's clarity, phosphorus and algae readings: lakes with low nutrient readings and American Eel documented are the best places to start for recreational targeting.
