About this map

The Colusa riverfront and its surrounding agricultural basin represent a sophisticated water management landscape along the Sacramento River. In the town center, civil structures like the Colusa County Courthouse and its County Courthouse Annex sit near the river's edge, reflecting the community's role as a regional seat of government. To the west, the flat terrain of the Central Valley is crisscrossed by an extensive network of waterways, including the Colusa-Trough Main Canal and the Cheney Slough Irrigation Canal, which are vital to the area's intensive farming.

Legacy landmarks such as the Colusa Cem District and Holy Cross Catholic Cem provide important reference points for genealogists. The map also captures the river's dynamic morphology at Cobbs Bend and Arnold Bend, while aviation history is represented by Davis Airport. This modern survey illustrates how the grid-style development of settlements like Williams integrates with the older slough systems like Hopkins Slough and Powell Slough.
