The Brazos River Authority was the first agency in the country to be tasked with managing the water resources of an entire river basin.
The BRA currently holds water rights issued by the State of Texas for a System of reservoirs, a 30 percent share in a proposed reservoir,
and its System Operation Permit. Collectively, these rights authorize the BRA to supply approximately one million acre-feet of water
from the Brazos River basin annually for municipal, industrial, agricultural and mining purposes.
BRA’s water supply reservoirs, Possum Kingdom Lake, Lake Granbury and Lake Limestone were constructed and are owned and operated by
the Brazos River Authority. A fourth reservoir, Allens Creek, is a permitted water storage lake planned for construction in the
lower portion of the Brazos basin.
The eight US Army Corps of Engineers reservoirs were built for both flood control and water supply. The BRA leases water supply
storage space from the federal government in Lakes Proctor, Whitney, Aquilla, Belton, Stillhouse Hollow, Georgetown, Granger, and
The BRA operates two pipeline systems to transport water from reservoir storage to areas where it is needed. The Williamson County
Regional Raw Water Line links Lake Stillhouse Hollow in Bell County and Lake Georgetown in Williamson County. The East Williamson
County Water Transmission Line moves water supply from Lake Granger to a potable water treatment plant.
