Until 2011, Oklahoma NRCS had provided financial and technical assistance for the decommissioning of only two flood control dams: Cavalry Creek, Site 6 and Little Washita Creek, Site 13. Both dams had complex issues involving the presence of gypsum in their foundations. Multiple attempts were made to address the foundation issues at each site, but both structures faced an increased probability for dam failure due to seepage and internal erosion. In each case, decommissioning the structure was chosen as the alternative of last resort.
