Rough fish like Trout are often associated with eutrophic, nutrient-loaded waters. Their presence — documented in 104 Wisconsin lakes — is often a signal of how the rest of the fishery is functioning. Trout is moderately distributed — 104 lakes in Wisconsin. Some counties have it, others do not, so checking the per-lake pages matters.

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.
