East Fork San Jacinto River

The East Fork of the San Jacinto River originates in San Jacinto County and flows 46 miles through Walker County to Harris County, where it joins Caney Creek and the West Fork to create Lake Houston.

The East Fork is narrow and shallow with numerous sandbars and abundant overhanging branches and logjams. The abundant woody debris and sandy substrate provide habitat for a diverse community of macroinvertebrates and fish including minnows, gars, pirate perch, catfish, dusky darters, and several species of sunfish. The dense bottomland forest that surrounds the lower portion of the river provides habitat to many of the typical eastern woodland birds. The ecologically significant segment is from the confluence with Caney Creek in Harris County upstream to US 190 in Walker County. This segment is TNRCC stream segment 1003.
