TheSan Gabriel River is ariver that flows through centralTexas, USA. The San Gabriel River is formed inGeorgetown by the confluence of the North Fork San Gabriel and the South Fork San Gabriel, both of which originate inBurnet County. There are two major impoundments of the river:Lake Georgetown along the North Fork, andGranger Lake, about 25 miles (40 km) below the confluence. Both areU.S. Army Corps of Engineers impoundments. The San Gabriel River joins theLittle River[1] five miles south ofCameron which then meets theBrazos River northwest ofCollege Station. There is a city park in Georgetown at the confluence of the North and South Forks, with a well-known local swimming spot (the "Blue Hole") located just upriver from the confluence on the South Fork.
Like mostTexas Hill Country rivers, the San Gabriel west of theBalcones Fault is characterized by limestone river bottoms, some moderate rapids, small canyons, and muddy bottoms along slower-moving stretches; east of the Balcones Fault, the San Gabriel flows through theBlackland Prairie where rock features at the surface are more rare and the deep, clay soils are rolling to level and support dryland farms and more lush pastures than the thin soils to the west. Given the past tendency toward periodic large-scale but short-lived floods before construction of the large impoundments, much of the bottomland along the river banks east of Georgetown is forested with a mix of native oak and pecan plus other varieties, though in some locations pecan orchards with grafted varieties have been established as commercial enterprises. Two dams within the river formsLake Georgetown andGranger Lake.[2]
Recreational activities include canoeing, kayaking and fishing. Typical fish species found in the river arecatfish,largemouth bass,sunfish,carp,longnose gar and various species ofbait fish. However, many game fish and introduced species are found in the impoundments at Lake Georgetown and Granger Lake. The river runs through theApache Pass Amphitheater and Festival Grounds nearThorndale, south of the town ofSan Gabriel. Apache Pass features a cantilevered stage that projects out over the river and is used for major concerts and other events.
