2015 Map of Foster Island

About this map

The Sacramento River meanders through the heart of the northern Sacramento Valley, defining the intricate boundaries where Tehama, Butte, and Glenn counties converge. This 2015 survey reveals a dynamic riverine landscape characterized by significant water management and seasonal shifts, most notably evidenced by the massive Glenn-Colusa Canal cutting through the southern half of the map. The river's historical path has created a series of named islands and distinctive bends, including Foster Island, Wilson Island, and the curiously named Hoodlum Chute. To the east of the main channel, features like Dicus Slough and Soto Lake mark the low-lying floodplains. The terrestrial grid is dominated by agricultural roads like Cana Hwy and Wilson Landing Rd, reflecting the region's long-standing reliance on the fertile soils of the Central Valley.
