The Second phase 2B includes installation of 150 high-strength anchors for critical monoliths and the sacrificial bulkheads on the remaining penstocks.American Recovery and Reinvestment Act (ARRA) funding increased the number of anchors installed to 204, which will increase the elevation of flood waters that can be held by the dam.

The installation of apron drains in the stilling basin and reaming of gallery drains in the dam will increase stability.

In August 2009, Brayman Construction Corp began the construction work on the project and completed in 2011, and ARRA funding extended the completion date to 2011.
