Oregon Coastal Habitat Project Restores Coho and Reduces Flooding

NOAA’s work with community partners restoring estuary habitat in Tillamook Bay, Oregon is revitalizing tidal wetlands for threatened Oregon Coast coho salmon, and helping reduce flooding in the surrounding communities and farmlands.

 

NOAA’s work with community partners restoring estuary habitat in Tillamook Bay, Oregon is revitalizing tidal wetlands for threatened Oregon Coast coho salmon, and helping reduce flooding in the surrounding communities and farmlands.

The project’s benefits to fish were realized immediately—443 acres of different estuary habitats critical to juvenile salmon are now available, including mud flats, open water with vegetation, marsh and others. Often called “nurseries of the sea,” estuaries offer unique conditions, like slow moving water and tides that bring in nutrients, which keep fish safe and allow them to grow.

A recently published report also confirms the project’s flood reduction goals were achieved. Shortly after project completion, in October 2017, a flood occurred at the site. Our restoration work resulted in widespread reduction in flood levels and duration including along Highway 101, a key commercial and transportation corridor. In total, about 4,800 acres around the project site showed reductions in flood levels.

This project, like many others we work on, shows how restoring habitat back to its natural functions can help coastal communities be more resilient against severe weather. Nature-based approaches are being shown to provide these, and many other economic benefits, along both the the east and west coasts of the United States.
