How does one of the West’s busiest airports deal with extreme stormwater, and what does that mean for water quality standards in the rest of the state?

Pollution from stormwater has been called one of the greatest threats to Puget Sound. How much will it cost to hold back the rain? A new EPA-funded study says the price could reach billions per year, a figure that dwarfs current state and federal allocations.

Nature inspires new approach to flood control

Every year, winter rains bring the threat of millions of dollars in property damage, or even the loss of life, from floods. Rivers have historically been channeled and tamed to protect towns and farms in low-lying floodplains, but research shows that this approach may actually be making flooding worse while at the same time threatening Puget Sound’s salmon. At Hansen Creek in the Skagit Valley, scientists say nature is the best engineer. Read Eric Wagner’s story in the Encyclopedia of Puget Sound’s Salish Sea Currents series.

The decaying seawall along Seattle’s waterfront is providing scientists with an opportunity to improve long-lost habitat for migrating salmon. It could also show the way for habitat enhancements to crumbling infrastructure worldwide. One University of Washington researcher describes the project.

The latest issue of Salish Sea Currents reports that some of the greatest dangers to Puget Sound come from our common, everyday activities. These pervasive sources of pollution are so woven into our lives that they are almost invisible to us, but it’s becoming impossible to ignore their effects.

Traditionally, salmon restoration has focused heavily on spawning habitat in streams and rivers, but scientists say that may no longer be enough. New research presented at the 2014 Salish Sea Ecosystem Conference suggests that conserving and increasing high-quality habitat for juvenile salmon could be just as vital.
