Ocoee River: what state assessments show

Does not support healthy aquatic life.

Official state determinations under the Clean Water Act — about the waterway, not measurements taken today.

Ocoee River in the Ocoee basin is tracked by the state as 5 separately assessed stretches (most recent cycle: 2024). Below is every designated-use determination on record — and what hasn't been assessed.

Designated uses

Swimming & recreation

Meets state standards for swimming

Is it safe to swim here?

Aquatic life

Does not support healthy aquatic life (4 of 5 assessed stretches)

Can fish and aquatic insects live here?

A use the state didn't report is omitted rather than shown as passing. "Never assessed" means unknown — never clean.

Listed causes

  • flow regime modification (hydrologic alteration)
  • copper (metals (other than mercury))
  • iron (metals (other than mercury))
  • sedimentation/siltation (sediment)
  • zinc (metals (other than mercury))

A listed cause names what the assessment found in the water. It is not an attribution to any specific facility or source.
