Rivers
Brazos River
The Brazos River is the 11th longest river in the United States; its headwaters are in New Mexico, and it flows into the Gulf of Mexico. Most likely named the Tokonohono, the river was called “Rio de los Brazos de Dios” by Spanish explorers which translates to “The River of the Arms of God” in English; its modern name is simply the “Brazos River.”

Creeks and Streams
There are numerous creeks and streams which flow through Fort Bend County. Two of these streams have gauges on them: Big Creek and Dry Creek.
Big Creek
Big Creek begins south of Rosenberg and flows southeasterly 25 miles into the Brazos River in Fort Bend County. The creek is an old Brazos River channel with associated sloughs, bayous, oxbow lakes, and coastal prairies that are bordered by bottomland hardwood forest.1 This habitat provides an excellent opportunity for bird watching, as over 270 species of birds have been sighted in this area. Birds commonly seen here include purple gallinules, least bitterns, prothonotary warblers, barred owls, white-ibis’, herons, and egrets among others. Other wildlife that inhabits the area includes alligators, bobcats, raccoons, feral hogs, and gray foxes.2 The ecologically significant segment is from the confluence with the Brazos River in Fort Bend County upstream to State Highway 36 south of Rosenberg in Fort Bend County.
(1) Hydrologic Function- bottomland hardwood forest and associated wetlands perform valuable hydrologic function relating to water quality.
(2) Riparian Conservation Area- fringed by Brazos Bend State Park and is part of the Great Texas Coastal Birding Trail. [source]

Dry Creek
Dry Creek, intermittent in its upper reaches, rises on the Brazos River just northeast of Rosenberg in central Fort Bend County and runs southeast for eleven miles to its mouth on Smithers Lake. The vegetation along its banks consists mainly of mixed hardwoods interspersed with various prairie grasses. The variable terrain is surfaced by highly impermeable soil and calcareous clay.

Bessie’s Creek
Bessies Creek, also known as Best Creek, Best’s Creek, or Besses Creek, rises 1½ miles northeast of Monaville in central Waller County and flows southeast for thirty miles, through northern Fort Bend County, to its mouth on the Brazos River, three miles south of Fulshear. It crosses an area of moderate to steep slopes surfaced by sandy loam and clay that support hardwoods and crops. The creek was probably named for Isaac Best, an early settler of Waller County.
