Summary

[edit]
Description Underground blasting to excavate a portion of the new auxiliary spillway at Folsom Dam in Folsom, Calif., shown Oct. 28, 2013. Buried charges blast loose up to 40,000 cubic feet of solid granite per shot - about half the volume of an Olympic-size swimming pool. A total of 340,000 cubic feet of rock will be removed in the stilling basin this November. This phase of work will eventually connect the new concrete spillway with the American River. The spillway is designed to dissipate the energy of releases from the lake before they enter the river. Blasting began Oct. 24 and is expected to continue weekdays through November.
