The Trinity River upstream of Lake Livingston has steep muddy banks lined with elm, sycamore and willow trees.3 The river meanders through isolated areas and is fed by numerous scenic creeks that provide habitat to abundant fish and wildlife. The channel is wide and contains many sandbars that can be utilized for camping and day use.3 A variety of game fishes can be caught in this reach including freshwater drum, striped bass, white bass, yellow bass, flathead catfish, channel catfish, blue catfish, as well as a number of sunfish species. Also present are gar, shad, minnows, suckers, western mosquitofish, silversides, and dusky darters. The ecologically significant segment is from Lake Livingston in Walker/Trinity County upstream to State Highway 7 in Leon/Harris County. This is within TNRCC segments 0803 and 0804.
