About this map

McMillan and Big Valley anchor this Central Texas landscape where the meandering Colorado River defines the local topography. This 2013 survey reveals a rural territory structured by family history and water management, evidenced by the McMillin Cem and Lower Valley Cem. The terrain is characterized by distinct elevations such as Wildhorse Mtn, Round Mtn, and the Mauldin Hills, which overlook a network of seasonal watercourses including Horse Cr and Rocky Cr.

Modern infrastructure for water conservation is prominent in the southwest, where a series of impoundments—Lower San Saba Watershed Reservoir Number 10, Number 11, and Number 12—manage the drainage of Merriman Br and Jerrys Br. The map also documents a complex grid of rural routes like Shaw Bend RD and Catclaw RD, providing a precise record of land use and property access in San Saba County at the start of the 2010s.
