Newhalem Penstock Saddle Replacement
Contact: Lisa Williams - Project Manager
PROJECT UPDATE (9/19/2017):
This project has been completed. Learn more about this project on our Power Lines blog.
A Seattle City Light contractor will be replacing 52 deteriorating, wooden saddles that support the Newhalem Penstock with new, cast-in-place concrete saddles. The penstock is a pipe that delivers water from the creek to the hydro turbines that are located inside the Newhalem Powerhouse. The water turns the turbines, which eventually produces electricity.
Map of the Construction Work Area
- The old saddles no longer safely support the penstock. The new saddles will provide structural stability and protect the integrity of the penstock.
- The Newhalem Penstock is located on the south bank of the Skagit River, in the town of Newhalem, WA. The project is within the Ross Lake National Recreation Area, which is part of the North Cascades National Park Complex.
PROJECT IMPACTS & TIMELINES
- Trucks will use the access road to Loop C and Group Sites A and B of the Newhalem campground. All park facilities will remain open during construction.
- At times, a helicopter may be used to deliver materials and concrete to the site. Park users may encounter additional noise.
- The Trail of the Cedars will be open during construction. It will be rerouted around the construction site.
