The importance of estuaries for adult salmon in Puget Sound
Next time you see a salmon moving upstream to spawn, consider the importance of estuaries. Estuaries, places where rivers and creeks mix with the waters of Puget Sound, help salmon adjust the ions (salts) in their bodies so they can safely make the transition from marine to fresh water. A new report by University of Washington scientist […]

Ask a scientist: What is a distributary channel?
In a natural state, a river passing through a floodplain will have many side channels and tendrils that distribute the water, fanning it out across the delta. However, these channels are often lost when rivers are diverted to make room for farmland or other human development. In many cases, even after the dikes and levees […]
