Lake Whitney, Reservoir in central Texas, United States.

Lake Whitney is a large reservoir in central Texas spanning Hill County and Bosque County. The reservoir sits on the Brazos River and is surrounded by wooded shores that give way to rolling hills and rocky bluffs.

Congress authorised the Whitney Reservoir project in 1941, but funding was diverted to World War II and work only resumed under the Flood Control Act of 1944. Construction of the dam began in May 1947 and the Brazos River was impounded in December 1951; the powerhouse was built from April 1951 to June 1953. The site had earlier held Towash Village, a Hainai settlement whose people moved upstream when Anglo-American settlers arrived in 1850.

The reservoir lies on the Brazos River at River Mile Marker 442, and its name comes from the town of Whitney in Hill County. The Hainai people, who migrated from Louisiana in 1835, had a village called Towash Village on these banks, named for their chief; Anglo-American settlers displaced it in 1850. In 2005 the Texas Legislature designated the area the Getaway Capital of Texas, a title reconfirmed in 2011 by House Concurrent Resolution No. 83.

The reservoir lies on the Brazos River at River Mile Marker 442, about 2,000 km west-southwest of Washington, D.C., and close to the Interstate 35 corridor between Dallas and Fort Worth. Access is by road; the lake stretches roughly 29.7 km north to south and 16.7 km east to west. Anglers should check golden algae bloom status with Texas Parks and Wildlife before fishing.

The McCown Valley Equestrian Area offers a riding route of about 12.5 miles (20 kilometers) that winds through hilly terrain beside the water. This trail is one of the few in the Texas state park system specifically laid out for horseback riders.
