The Department of Water Resources (DWR), along with State and local partners, celebrated the groundbreaking of the Delta’s largest tidal wetlands restoration project. The Dutch Slough Tidal Marsh Restoration Project will re-establish a rich ecological network that will boost survival rates of endangered fish and wildlife while also protecting neighborhoods against flooding.
The Dutch Slough site is located in the City of Oakley, eastern Contra Costa County, in the western Delta. The site encompasses 1,178-acres, and is bound by Dutch Slough on the north, Marsh Creek on the west, the Contra Costa Canal on the south, and Jersey Island Road on the east. The site comprises three parcels, partially separated by Emerson Slough and Little Dutch Slough.
Construction on two of the parcels, Emerson and Gilbert, started in May 2018 and is expected to be completed in 2019, followed by revegetation planting. Restoration of the third parcel, Burroughs, would begin in 2020.
