JONES CREEK (Brazoria County). Jones Creek rises ten miles southwest of Angleton at Clemens State Farm in southwestern Brazoria County (at 29°01' N, 95°30' W) and flows twelve miles southeast, forming Jones Lake just before its mouth on the Gulf Intracoastal Waterway^qv (at 28°53' N, 95°25' W). The original course of the stream has been altered by a channel in its upper reaches. According to the 1936 county highway map, Jones Creek originally flowed into Cedar Lake. The creek is named for Capt. Randal Jones,^qv who was involved in the battle of Jones Creek.^qv The local terrain is flat and is surfaced by clay and sandy loams that support water-tolerant hardwoods, conifers, and grasses. At the stream's mouth, brackish to saltwater coastal marsh, made up of mud and sand, supports rushes and grasses.
