The Conchas Lake Project was authorized by the U.S. Congress in 1935. Construction of the dam began in 1936 and was completed in 1938. The dam was built to provide irrigation water for the surrounding area, as well as to control flooding on the Canadian River. The reservoir created by the dam, Conchas Lake, is the largest lake in New Mexico. It covers an area of over 20,000 acres and has a capacity of over 1 million acre-feet of water.
The dam is also a popular recreation spot. It is home to a variety of fish species, including bass, catfish, and walleye. There are also several campgrounds and boat ramps located around the lake. Visitors can also enjoy swimming, boating, and fishing.
