In 2020, engineers pumped 225,000 cubic yards of dredged sediment into the Columbia River; it became four new islands now being studied as salmon habitat

In an exciting environmental initiative, dredged sediment is being repurposed to form new islands aimed at habitat restoration. Engineers have meticulously placed this sediment to construct islands and adjacent channels along the river. Researchers are examining these man-made islands to gauge their impact on supporting wildlife, especially juvenile salmon. This pioneering technique may pave the way for future efforts in restoration ecology.
