Grand Coulee Dam's Open Spillways
Clip: Season 24 Episode 6 | 15s
More than a mile long, the Grand Coulee Dam is the largest concrete structure in the U.S. In the fall of 2011, dam operators agreed to open the spillway just for American Experience. "It was very exciting that they agreed to spill for us for a short period specifically for the film," said Associate Producer Lauren DeFilippo. "We ran to the top and bottom [of the dam] in about 30 minutes."
