Current tour plans (August 18) include presentations from US Army Corps of Engineers related to high hazard dams in the Cumberland River Basin, and a workshop "Methamphetamine as a Community Crisis in Tennessee".

US Army Corps of Engineers & Tennessee Valley Authority disaster mitigation history and current plans for high-risk dams. Both river systems include high-risk dams. The USACE Wolf Creek Dam is an earthen and concrete structure more 5,736 feet long and impounds Cumberland Reservoir, the largest reservoir east of the Rocky Mountains and 9th largest in the U.S. The reservoir’s capacity of more than 6,000,000 acre-feet exceeds the total volume of all other reservoirs in the Ohio River Valley. The TVA Fontana Dam, built 1942-1944, is the largest concrete dam east of the Rocky Mountains at 480 feet high and 2,365 feet long.

Even minor oversights can be quite interesting and disruptive. See what happens when a barge loaded with hazardous materials gets hung up on the lock gate:
