"The 7,400-foot-long dam consists of a low concrete apron and sill surmounted by tainter gates separated by 10-foot concrete piers....Twelve 60- by 21-foot tainter gates are provided for the structure. The lock has a 110- by 600-foot chamber of the single-lift type with miter gates. The lock has a 20-foot normal lift and 22-foot maximum lift." [

"The Tulsa District has recently reopened W D Mayo Lock & Dam 14 following flooding caused by heavy rainfall throughout the district in May 2019. The Arkansas River submerged a large section of L&D 14, which regulates flows for the McClellan Kerr-Arkansas River Navigation System in Oklahoma. When the floodwaters receded thousands of cubic yards of sediment and trash were deposited in the lock and surrounding facilities."
Another insight into the extent of the 2019 flooding.

Open river usually starts at 146,000 cfs. The river is moving at about 20-25 mph. There is 15' clearance when the gates are completely open. There are a lot of gate changes here because the upstream powerhouse runs on demand. |

Massman led the Massman-Al Johnson-Kiewit joint venture that constructed the complex, including a 110 by 600-foot lock chamber and a 7,400-foot-long dam featuring twelve tainter gates. The project broke ground in 1966 and utilized a staged series of cellular sheet pile cofferdams to ensure safe access to the work area. It was dedicated on October 24, 1970, at a ceremony attended by former President Lyndon B. Johnson and approximately three thousand additional guests.
