Spotted Sucker Lakes in Michigan

Rough fish like Spotted Sucker are often associated with eutrophic, nutrient-loaded waters. Their presence — documented in 7 Michigan lakes — is often a signal of how the rest of the fishery is functioning. Spotted Sucker is narrowly distributed — only 4 lakes in Minnesota and 3 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 Spotted Sucker lake list below against each lake's clarity, phosphorus and algae readings: lakes with low nutrient readings and Spotted Sucker documented are the best places to start for recreational targeting.
