There's some amazing video of high voltage electricians dangling from helicopters flitting from transmission tower to transmission tower disconnecting equipment in case the emergency spillway gives out.

There's other video of a lone guy manipulating the nozzle of a cement pumper gluing thousands of tons of granite boulders together on one side of the reservoir near the dam itself.

The emergency spillway has split in two and is threatened by undermining at the bifurcation.
