ELM FORK OF THE TRINITY RIVER. The Elm Fork of the Trinity River rises just south of Saint Jo in eastern Montague County (at 33°42' N, 97°33' W) and runs southeast for eighty-five miles, through Cooke and Denton counties, to its confluence with the West Fork of the Trinity just west of downtown Dallas in central Dallas County (at 32°48' N, 96°54' W). In 1928 the stream was dammed in central Denton County to form Lake Dallas, which had a capacity of 194,000 acre-feet. In 1955 a new, considerably larger, dam was completed. The lake, originally known as the Garza-Little Elm Reservoir, was renamed Lewisville Reservoir in 1960. The stream traverses generally flat to rolling terrain surfaced by shallow, stony loams that support junipers, oaks, and grasses.
