06/30/09 - Ballard Locks

We happened to catch the Ballard Locks in action. There was a tugboat pulling a pair of barges and a host of smaller craft in the lock waiting for their trip down to the level of the Puget Sound. After a bit, they closed the far gate of the lock. Then, the bells rang, and the lock drained. When the water level in the lock matched the lower level, they opened the gate and let everyone out. It doesn't sound like much, but it is kind of amazing to watch. It works just the way it does in those science book illustrations.
