Kimberly Peeples, commander and district engineer of the Great Lakes and Ohio River Division, on work he and other employees have been doing at the lock in New Kensington, Pennsylvania, April 13, 2022. Nuss led a project to replace more than 700 feet of hydraulic pipes that will save the district more than $150,000 in contracted costs. The hydro lines control the opening and closing of gates and valves for lock operations. (U.S. Army Corps of Engineers Pittsburgh District photo by Michel Sauret)
