As if you needed to better understand the importance of rain gardens, stormwater runoff and salmon, after my last post, here’s the next thing in my inbox. Another recent experiment that shows the affects that stormwater has on aquatic species.
Just hours into the experiment, the prognosis was grim for salmon that had been submerged in rain runoff collected from one of Seattle’s busiest highways. One by one, the fish were removed from a tank filled with coffee-colored water and inspected: They were rigid. Their typically red gills were gray….. This was the fate of coho salmon exposed to the everyday toxic brew of dirt, metals, oil and other gunk that washes off highway pavement after rains and directly into Puget Sound. Phuong Le reports.
