A win-win project for people, nature and our treasured salmon

When a popular recreational trail on the Olympic Peninsula was damaged by a flood and closed last February, there were two options: either 1) fix the trail for walkers and bikers, or 2) fix the trail for walkers and bikers AND do it in a way that improved fish habitat and reduced flood risk. The choice was obvious: build a project with many positive outcomes.
The Olympic Discovery Trail is a rails-to-trails system that currently extends from Discovery Bay to Port Angeles and receives 100,000 visits per year. When a portion of the trail over the Dungeness River near Sequim was damaged, walkers and bikers were anxious to get it fixed quickly. Randy Johnson, Habitat Program Manager with the Jamestown S’Klallam Tribe, saw a great opportunity for a win-win-win project, but he had to act fast to make sure the project could incorporate benefits to fish and flooding, and get the trail back in use.
The damaged section was part of a 585-foot-long trestle supported by creosote pile structures every 16 feet across the floodplain. Fill had been placed across an additional 165 feet of floodplain to meet the pile-supported trestle. These structures caused a major blockage, wracking up wood, blocking flood flows and requiring that the river be “trained” to go under a bridge. This essentially forced the river into one place and cut it off from the floodplain. Healthy rivers move around in their floodplains, creating vital habitat for fish, storing floodwater and keeping people nearby safe. These processes had been severely limited by the trestle and fill.
Because the project had several positive outcomes and support from various stakeholders, it moved forward quickly. Using funding from Floodplains by Design, Salmon Recovery Funding Board, Bureau of Indian Affairs Climate Adaptation fund and other sources, the design was completed, permits were obtained and construction was underway before the end of August. By early October, the old pilings had been removed and new footings to support a just a few concrete posts - 180 feet apart instead of 16 feet apart - were being constructed.
By December 2015 the reconstructed trail will be completed, allowing the river access to an additional 750-foot-wide floodplain. Recreational trail users will be able to get back on the trail. Viewing platforms will allow groups of students and birders to gather out of the way of walkers and bikers, and take in the river and its wilder inhabitants.
This year there has been a large number of pink salmon returning to the Dungeness River to spawn. When we toured the project site in early October, the river was alive with fish hovering over their redds. As an avid biker myself, I love that there are trails like this where I can look down and see salmon spawning.
The Olympic peninsula provides critical habitat for several species of threatened salmon. The last few years have seen some big restoration projects completed, between JimmyComeLately, the Elwha River Dam removals, and now several projects along the Dungeness River and estuary. It’s inspiring to see the impact these big projects are having on restoring salmon habitat.
