Corps drills into Cottage Grove during investigation
The U.S. Army Corps of Engineers Dam Safety team is conducting a geotechnical investigation at Cottage Grove Dam, which includes boring into the dam. Cottage Grove Dam is located on the Coast Fork of the Willamette River south of Eugene Ore. The work is part of a larger geotechnical assessment where data from the borings will provide information on the physical properties of the dam. The Dam Safety team will then use the data to study how the dam will perform under various conditions.
