the two closed tunnels with explosives but were unsuccessful. On 10 May, when the reservoir reached the power station intake, engineers began releasing water through the unfinished power house to prevent a breach of the dam. On 12 May one of the previous sealed tunnels naturally reopened, which suddenly increased downstream flows by three times the average. This promoted evacuations downstream, eventually totaling around 25,000.

September 2011 and it is expected to be complete in 2013. Main works will begin thereafter and the power plant is expected to being commissioning in 2018. Development of the project is being proposed by EPM Ituango, a consortium of Empresas Publicas de Medellin (EPM) and the Antioquia government. The total cost is expected to be US$ 2.8 billion.

The dam's feasibility study was completed in 1983 but the project was shelved in the 1990s due to an economic crisis. The final designs for the project were finished in 2008 and on 8 July 2011, the project management contract was awarded. Preliminary construction (surveying, roads, bridges, diversion

On May 16 silt build-up in a portion of the power house, the only means to drain the reservoir, led to water escaping into a transit gallery used by construction vehicles. The water eventually poured onto the downstream face of the dam, eroding the roadway and a portion of the
