Conchas Dam, Gravity dam in San Miguel County, New Mexico, US.
The Conchas Dam extends 19,500 feet across the Canadian River, reaching a height of 235 feet with concrete gravity sections and earthen wing dikes.
Construction of the dam commenced in 1935 under the Emergency Relief Appropriation Act, providing employment opportunities during the Great Depression until its completion in 1939.
The dam created Conchas Lake, which serves as a recreational center for activities including fishing, boating, water skiing, swimming, and a 9-hole golf course.
The structure maintains a permanent pool of 61,532 acre-feet and extends its flood-control capacity to 709,119 acre-feet, supporting the Tucumcari Irrigation Project.
The dam controls water distribution through 300 miles of canals, enabling irrigation for 41,400 acres of agricultural land in the Canadian River valley.
