2015 Map of Williams

About this map

The town of Williams serves as the primary hub of activity in this portion of Colusa County, where the grid of city streets like N St and H St meets the modern alignment of the Interstate and the traditional path of Old Highway 99W. The surrounding landscape is defined by an extensive network of agricultural irrigation and drainage, anchored by the Glenn-Colusa Canal and supported by numerous natural waterways including Freshwater Cr and Salt Cr. Smaller rural localities such as Cortena and Delphos sit along the north-south transit corridor, marking points of interest in a region primarily dedicated to large-scale cultivation. This 2015 survey illustrates how traditional water management systems like the Freshwater Lateral and Glenn Valley Slough continue to shape the development of the Sacramento Valley, preserving the distinct boundaries of the Public Land Survey System that organize the area into neat sections.
