  • A time- lapse video shows the construction of the Folsom Dam auxiliary spillway in Folsom, Calif., from April 2013 to March 2014. Excavation began in 2011 to remove 3.8 million cubic yards of rock and soil from the site. In 2012, the first steel and concrete were placed for the control structure—essentially a second dam—that will stand as tall as the Statue of Liberty when completed. In March, the first of 12 massive gates were delivered to the construction site and will be installed in 2014. The project is scheduled to be completed by October 2017 and is the centerpiece of a broader multi-agency effort to modernize Sacramento's flood control infrastructure and reduce flood risk for the region.

  • While construction continues around the clock on the new auxiliary spillway at Folsom Dam, the massive gates for the spillway's new dam are being built near Portland, Ore. Join us for a routine quality assurance check before they make their 600-mile journey to Folsom, Calif., for installation beginning in summer 2014. Available in High Definition.
  • Basalt rocks ranging in size from 1-4 feet in diameter are trapped below the spillway at Bonneville Dam. The U.S. Army Corps of Engineers needs to remove the rocks -- about 550 cubic yards -- before the Spring spill season begins. When water spills over the spillway, the rocks move in a fashion known as "ball milling" which erodes the concrete. The rocks entered the spillway in 2011 when the Columbia River experienced significant high flows during most of the Spring and Summer.
  • In Folsom, Calif., Folsom Dam's new auxiliary spillway project transforms rock and dirt into a massive flood risk reduction project. It's one of the largest construction jobs in the nation and crews are working around the clock to complete this critical infrastructure project by fall of 2017. Join us for an inside tour of the construction.
