Petaluma_River

The Petaluma River is a river in the California counties of Sonoma and Marin that becomes a tidal slough for the majority of its length. The headwaters are in the area southwest of Cotati. The flow is generally southward through Petaluma's old town, where the waterway becomes navigable, and then flows another 10 mi (16 km) through tidal marshes before emptying into the northwest corner of San Pablo Bay.
