Meramec River - Ecology

Ecology

At one time, the river was listed as one of the most polluted rivers in Missouri. Local and state government along the river have taken tremendous steps in cleaning it up. Today the river is one of the most diverse waters in Missouri. The river is plentiful in; black crappie, channel catfish, flathead catfish, largemouth bass, paddlefish, rainbow trout, brown trout, rock bass, smallmouth bass, walleye, white crappie, and some of the richest mussel beds in the state. The endangered Eastern Hellbender (Cryptobranchus alleganiensis alleganiensis) also lives in the river.

The Meramec River includes one of only three Red Ribbon Trout Areas in the state of Missouri, boasting a healthy rainbow trout population and an impressive brown trout population. Red Ribbon trout streams are managed by the Missouri Department of Conservation to produce trophy-sized fish.

Maramec Spring is the fifth-largest spring in Missouri. Maramec Spring Park, south of St. James, is the home of an historic iron works and trout fishery.
