Safety Tips

Non-motorized small boaters need to be aware that the river is tidal and currents and winds can be strong.

Wildlife Tips

The marshes found along the Petaluma River are habitat for sensitive species, including Ridgway’s rail and black rail. To protect marsh species boaters should avoid landing in marshes and entering narrow sloughs. The Water Trail recommends boaters maintain a buffer distance of 50 feet from rail habitat.
