Canton Lake is a lake in Blaine and Dewey counties in Oklahoma, near Longdale and Canton. Its main source of water is the North Canadian River. It's about an hour away from Enid.
Canton Dam was a 1948 project of the Southwestern Division of the United States Army Corps of Engineers. The earthen structure is 68 feet (21 m) high and 15,140 feet (4,610 m) long at its crest, with a maximum storage capacity of 383,000 acre-feet. The lake has a shoreline of 45 miles (72 km). Both dam and lake are owned and operated by the Corps of Engineers.
The lake is home to several species of fish including largemouth bass, white bass, channel catfish, crappie and walleye. Canton has become the primary source of walleye eggs for incubation and stocking of other state lakes. Since 1968, community leaders and local merchants have promoted an annual Walleye Rodeo. The four-day event offers visitors the chance to win cash and other prizes that total over $30,000.
Facilities at the lake include boat ramps, picnic areas, RV and tent campsites, drinking water, group shelters, restrooms, showers, a swimming beach, concession services and a nature trail.
In early 2013, Oklahoma City officials diverted 30,000 acre-ft of water from Canton Lake to Lake Hefner, to replenish the city's water supply. Later, spring rains replenished the level of that lake, which had to dump water into the North Canadian River to prevent the lake from overflowing. However, the effect was to leave Canton Lake 13 feet (4.0 m) below its normal level. This has contributed to an algae bloom.
In April 2016, the lake finally replinished from the 2013 water diversion Oklahoma City made.
