Trout-perch Lakes in Michigan

Rough fish like Trout-perch 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. Trout-perch is narrowly distributed — only 7 lakes 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 Trout-perch lake list below against each lake's clarity, phosphorus and algae readings: lakes with low nutrient readings and Trout-perch documented are the best places to start for recreational targeting.
