River Intake in Gladstone

The cofferdam support structure is under construction on the Clackamas River.  A cofferdam is a watertight enclosure pumped dry to allow construction work to happen below the waterline and to protect wildlife and endangered fish habitat. 

The Army Corps of Engineers' permit allowed construction in the river only during certain times of the year to protect important fish habitats. Crews are hard at work creating this dry area where construction work can continue throughout the year without wildlife impacts.

Once the cofferdam is finished, any remaining water will be pumped out. Check back over the next few weeks to monitor the construction progress.
