South Slough National Estuarine Research Reserve

Marsh in Oregon's South Slough National Estuarine Research Reserve was diked in the early 1900s, leading to soil subsidence. This project aimed to restore salt marsh function and establish marsh channels to support fish habitat. The dike was removed and material from the dike was used to raise marsh elevation through thin layer placement. This project deposited 10,000 cubic meters of dredged material onto a 5-acre stretch of marsh. This project led to successful marsh vegetation recovery as well as formation of tidal channels at lower marsh elevations. These channels benefited fish communities.
