About this map

The Petaluma River winds through a complex network of wetlands and sloughs in this 2012 survey, defining the geography between the northern reaches of San Pablo Bay and the growing outskirts of Petaluma. This tidal landscape is a maze of named waterways including Schultz Slough, Tule Slough, and Mud Hen Slough, which surround landforms like Neils Island and Hog Island. The transition from riverine marsh to upland is marked by Burdell Mountain and the settlement of Burdell near the southern edge, while San Antonio and Lakeville anchor the eastern and western flanks of the waterway.

Transportation and infrastructure weave through the valley, with the Lakeville Hwy and various ranch roads like Twin House Ranch Rd providing access to the fertile lowlands. The presence of Gnoss Field and Mazza Airport indicates the region's role in local aviation. Historic landing sites such as Haystack Landing and the McNear area reflect a long history of river-based commerce and transport that continues to shape this corner of Sonoma and Marin counties.
