About Hayward Regional Shoreline

Salt, fresh, and brackish marshes along the Hayward bay shore with public trails. Source

Hayward Marsh, completed in 1985, is a 145-acre fresh and brackish water marsh and is somewhat unusual in that it relies on secondary treated effluent as the freshwater source. The marsh is made up of five managed ponds and has 15 islands that are utilized by many species of nesting birds.
