Gavins Point Dam no release

Pam Simmons of Crofton, Neb., takes a photo at Gavins Point Dam near Yankton, SD., Wednesday, May 9, 2012. The Army Corps of Engineers stopped the flow of water from the dam to allow crews to inspect the structure for any possible damage from last summers floods. The Missouri River at Yankton dropped over eight feet as crews used ground penetrating radar and drilled test holes to check for damage. Releases through the dam were expected to be at zero for about eight hours.. Sioux City Journal photo by Tim Hynds
