Divers perform inspection of Ice Harbor’s Removable Spillway Weir

For the Corps of Engineers, the onset of colder weather signals the beginning of dive season. While perhaps not an official season, most dive work is scheduled between November and March, when salmon runs are at their lowest. On November 17, a team of divers suited up at Ice Harbor Dam to perform the required 3-year inspection of the Removable Spillway Weir.

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.
