A US$307M plan has been announced to repair the Wolf Creek dam in Kentucky, US, after leakages were discovered in the dam's foundations.

The plan – outlined during two public meetings held by the US Arms Corps of Engineers (USACE) – involves the installation of a concrete wall to stabilise the dam. The wall will reinforce a previous concrete structure completed in the early 1970s to combat similar leakage problems.

Significant lowering is not expected in Lake Cumberland, which is held back by the dam.
