PILOT GROVE CREEK
PILOT GROVE CREEK. Pilot Grove Creek rises in southeastern Grayson County (at 33°31' N, 96°26' W) two miles west of Whitewright. The East Branch of Pilot Grove Creek rises one mile west of Whitewright (at 33°30' N, 96°25' W) and joins the main branch two miles north of the town of Pilot Grove (at 33°26' N, 96°26' W). The West Branch rises near the town Tom Bean (at 33°31' N, 96°29' W) and runs southeast for six miles to its mouth (at 33°27' N, 96°27' W) on the main branch a mile west of Pilot Grove. The stream, which is intermittent in its upper reaches, runs south for thirty-four miles through Grayson and Collin counties before emptying into Lake Lavon in central Collin County (at 33°07' N, 96°27' W) a mile east of Culleoka. The major tributaries of Pilot Grove Creek include Desert and Sister Grove creeks. The stream traverses flat terrain surfaced by clay and sandy loams that support water-tolerant hardwoods, conifers, and various grasses. The region historically has served as crop and range land.
