Remote Operated Vehicle sent from Portland to do inspection at McNary

The Columbia River was a deep shade of ocean blue, and the sky was surprisingly clear and sunny for a November afternoon. A perfect day for a dive. On top of McNary dam, on November 4, two men unloaded a large, green remote operated vehicle (ROV) from the back of their trailer. The task for the day was to send the ROV down on the upstream side of the dam to conduct an inspection.
