Brook stickleback Lakes in Minnesota & Wisconsin

Other SpeciesFound in 24 lakes

Rough fish like Brook stickleback are often associated with eutrophic, nutrient-loaded waters. Their presence — documented in 24 Minnesota and Wisconsin lakes — is often a signal of how the rest of the fishery is functioning. Brook stickleback is narrowly distributed — only 0 Minnesota lakes and 24 Wisconsin lakes 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 Brook stickleback lake list below against the LakeGrade rubric: lakes with both an A or B grade and Brook stickleback documented are the best places to start for recreational targeting.
