Foundational erosion at beautiful Wolf Creek Dam

Nashville, take note.

Since the 1960s when they discovered the problem, a foundational problem, the Army Corp of Engineers has tried to reinforce this remote Kentucky dam that was built over porous and erodible limestone rock. It turns out this was the wrong place to build a dam. The karst geology of extremely porous and cracked limestone that surrounds this area has resulted in a constant dissolution of the dam's rock foundation when water is above it. Over the years, the dam has had near failures. So far, no matter how much engineers have tried to fix it by adding safety structures to the dam, uncontrolled water seepage erodes the dam's geological foundation. In its defense, the dam has lasted some 70 years without collapse. The ultimate solution is either to have no dam, which would result in a loss of flood control and hydroelectric power; or, build another dam somewhere else on better ground. But that would be very expensive. Tax payer dollars.

Way down the Cumberland River lies the bustling downtown of Nashville, Tennessee. Music City.

This is a lovely lake though. Scenic. Kentucky boaters love it.
