Natural history The river continues to be utilized for commercial navigation on a smaller scale than during its "steamboat" days. It is fed by numerous small creeks containing endemic native fish such as killifish. Fishing remains popular in the river for black bass, white bass, bream, freshwater drum, and gar. Concerns about airborne mercury contamination in some areas discourage consumption of the fish for food. Fishing for rainbow trout is popular in the tailwaters of Lakes Ouachita, Hamilton and Catherine in and around Hot Springs, Arkansas. The river is commercially navigable from Camden, Arkansas, to its terminal point in Jonesville in Catahoula Parish in eastern Louisiana. Upstream of Camden, the river receives substantial recreational use. The Ouachita is lined for most of its length with deep woods, including substantial wetlands. It has a scenic quality representative of the southwestern Arkansas and northern Louisiana region.
