Yesterday, the Eugene Dive Club ventured up to the mountains to dive the Smith Reservoir outflow. More details about this site are available in a trip report I posted a few years ago:

This really is a unique experience as it's tough to go faster than this underwater without a submarine. Here's a link to a video I shot on one of my runs through the current yesterday:

Not the best video, but it's a bit of a challenge to control my dual strobe Oly rig in the current. Afterwards, I played around in the shallows a bit and got some shots of dogs in the water. All in all, it was a pretty fun day.
