Port Susan program manager Kat Morgan says the project will improve habitat for salmon, waterfowl and other creatures that need a mix of salt and fresh water. The $4 million project includes rebuilding another dike for flood protection.
The Daily Herald reports the old dike was built in the 1950s by a farmer, the son of a Dutch immigrant. The environmental group bought the property in 2001 from his estate for $2 million.
The old dike may be breached in October.
