1440 acres of ponds along Alviso Slough, Ponds A8, A7 and A5, are connected to the Bay via 1 gate (on a new 8-gate dam), enhancing the ponds for ducks, pelicans and cormorants, and taking the first small step toward restoring marsh. The structure allows careful control of water flows in this mercury-laden area to minimize toxin impacts to wildlife.
