The Upper Nisqually River Levee Retrofit project added deflectors to the bank of the Nisqually River. The deflectors reduce water velocity and direct water away from the shoreline, slowing shoreline erosion and reducing damage to the levee. The Nisqually River is fed by the Nisqually Glacier in Mount Rainier National Park and flows along Route 706 and the town of Ashford, which connects visitors to the park via the Nisqually Entrance. Washington Rock produced nearly 7,000 tons of levee rock specifically for this project. Each piece of levee rock weighed between 6 and 15 tons. Washington Rock also provided over 1,500 tons of tailings and base course.
During construction, the river was diverted away from the levee. This picture was taken a year later, just outside the boundary of Mt. Rainier National Park. The park is visited by about 2 million people every year, and the Nisqually Entrance is the most popular point of access. It was interesting to visit a year later and see how the river and local wildlife have interacted with the deflectors.
