Located in Norther California, the Monticello Dam’s spillways are the largest in the world. Shaped as a funnel, the spillways allow water to bypass the dam when capacity is reached, preventing flooding and possibly saving a life or three. The Monticello spillways can swallow up to 48,400 cubic feet of water PER SECOND, creating some killer rips, dude.
