Lake Meredith, Reservoir in Texas Panhandle, United States.

Lake Meredith is a reservoir on the Canadian River in the Texas Panhandle, about 30 miles northeast of Amarillo, held back by Sanford Dam at Sanford. Its long, narrow shape branches into numerous coves, with five beach areas and boat ramps at Sanford Yake, Cedar Canyon, Fritch Fortress, Harbor Bay and Blue West. The water turns reddish-brown with pale swirls in places, and the surrounding terrain is flat and mottled brown and grey.

Sanford Dam was built between 1962 and 1965 by the Bureau of Reclamation, creating the reservoir on the Canadian River to supply drinking water to eleven regional cities, including Amarillo and Lubbock. The recreation area was first called Sandford Reservoir and was renamed Lake Meredith in 1972 for Austin A. Meredith, the Borger city manager who devised the dam concept and died two years before completion. It became a National Recreation Area in 1990.

The lake is named for Austin A. Meredith, city manager of Borger, who devised the dam concept and died two years before Sanford Dam was finished in 1965. The recreation area was renamed in his honour in 1972, and in 1990 it became Lake Meredith National Recreation Area, managed by the National Park Service together with nearby Alibates Flint Quarries National Monument from Fritch.

Several campgrounds sit directly on the shore and provide access to water activities. Visitors should know that water levels fluctuate significantly with seasons and rainfall.

In June 2008, the receding water exposed the wreckage of a Beechcraft Skipper that vanished on January 27, 1984, with pilot Steven Lampe, 25, and Larry Lucas aboard; there were no eyewitnesses to the crash. The lake fell to 26.14 feet on August 7, 2013, against a record 101.85 feet in April 1973.
