A drill crew will soon be on site at Cougar Dam, east of Eugene, Oregon, as the U.S. Army Corps of Engineers continues field investigation at some dams in the Willamette Valley.
The crews will also install instrumentation on the crest of Cougar Dam. The drilling and installation will require the eastbound lane across the dam to be closed intermittently. These closures will be from May 30 to June 13 between 7 a.m. to 6 p.m., reducing traffic to one lane.
