Northern Hog Sucker Lakes in Minnesota

Rough fish like Northern Hog Sucker are often associated with eutrophic, nutrient-loaded waters. Their presence — documented in 3 Minnesota lakes — is often a signal of how the rest of the fishery is functioning. Northern Hog Sucker is narrowly distributed — only 2 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 phosphorus and chlorophyll-a readings on: a rough-fish-heavy fishery often reflects an underlying nutrient-loading problem in the watershed. Cross-reference the Northern Hog Sucker lake list below against each lake's clarity, phosphorus and algae readings: lakes with low nutrient readings and Northern Hog Sucker documented are the best places to start for recreational targeting.
