Rehabiliation

Many of the early-constructed flood control dams in the state were built with a designed life span of 50 years. Oklahoma has 59 dams that were 50 years old by 2003. By 2005, that number will be 132; by 2010 it will reach 463; and by 2015, 1,090 or more than one half of the dams will have reached or exceeded their design life. Some dams need rehabilitation to ensure they continue to function as they were designed and remain safe.
