Williamson County
The area is divided into two regions by the Balcones Escarpment, which runs through the center from north to south along a line from Jarrell to Georgetown to Round Rock. The western half of the county is an extension of the Western Plains and is considered to be within the eastern fringes of Texas Hill Country; it has an average elevation of 850 feet (260 m). It features undulating, hilly brushland with an abundance of Texas live oak, prickly pear cactus, and karst topography. The eastern region of the county is part of the Coastal Plains and is flat to gently rolling with an average elevation of 600 feet (180 m). It consists of flatter land, with dark clay and rich, fertile soils for agriculture, but is quickly being developed as the county's population continues to increase and expand out. Williamson County is drained in the center and south by the San Gabriel River, which is the only river in the county, and in the north by creeks that run into the Lampasas and Little Rivers north of the county line.
