Whiskeytown Dam, Embankment dam in Shasta County, United States.

Whiskeytown Dam, officially Clair A. Hill Whiskeytown Dam, is a 282-foot (86 m) earthfill dam on Clear Creek about 6 miles (9.7 km) west of Redding. It impounds Whiskeytown Lake on the southern flank of the Trinity Mountains, holding 241,100 acre-feet (297,400 dam3) of water. Water arrives from the Trinity River through the 11-mile (18 km) Clear Creek Tunnel and leaves via lower Clear Creek and the Spring Creek Tunnel.

Construction began in August 1960 with clearing around the dam site, and by late 1961 more than half of the embankment was finished. The dam was topped out on February 7, 1963, and the reservoir began filling. President John F. Kennedy attended the dedication on September 28, 1963, speaking to over 10,000 people less than two months before his assassination. It was one of the first units built for the Trinity River Division of the Central Valley Project.

The dam's name preserves the memory of Whiskeytown, a Gold Rush settlement that now rests beneath the reservoir's water.

The dam sits in a mountainous area and is best accessed from the nearby visitor center. The surrounding area offers several trails and viewpoints where you can observe the structure.

The structure features a specialized overflow spillway system that manages massive water flows during high-water periods. This safety mechanism allows water levels to be controlled even under extreme conditions.
