Columbia, Snake & Clearwater River Cross Section Surveys

This project was completed in 2010 for the US Army Corps of Engineers. It involved hydrographic and topographic surveys of cross sections of wild, free flowing sections of 3 rivers located in Southeast Washington, Northeast Oregon, and North Idaho. Turbid water, extreme currents, and a lack of navigation charts made for some interesting boating and data collection, and some good photos.
