The Petaluma River is a tidal river that flows into San Pablo Bay and offers good fishing for striped bass—especially during the fall. White sturgeon, leopard sharks, and bat rays are also available closer to the bay. The tides significantly influence fishing conditions, and the optimal tides for fishing vary depending on the season. Popular fishing spots include the public docks in downtown Petaluma, Schollenberger Park, and the river’s mouth near San Pablo Bay, with key structures like bridges and docks often holding fish.
