Brushy Creek (San Gabriel River tributary)

Brushy Creek is a waterway located in central Texas, primarily in Williamson County. It is a tributary of the San Gabriel River, which itself is a major tributary of the Brazos River. The creek originates west of Round Rock, Texas, and flows generally eastward, passing through the cities of Round Rock and Hutto before emptying into the San Gabriel River.

The creek's watershed encompasses a largely suburban and agricultural area. Brushy Creek is known for its recreational opportunities, particularly along its greenbelt areas and within Brushy Creek Lake Park in Round Rock. These areas offer hiking, biking, fishing, and paddling activities.

Hydrologically, Brushy Creek is a dynamic system, experiencing periods of both low flow and significant flooding, especially during periods of heavy rainfall. Several flood control measures, including dams and detention ponds, have been implemented along its course to mitigate flood risk.

The creek's name, "Brushy," likely refers to the dense vegetation historically found along its banks. The creek and its surrounding area have seen significant development and population growth in recent decades, impacting its ecosystem and water quality. Efforts are ongoing to manage these impacts and protect the creek's natural resources.
