About this map

The Sacramento River meanders along the eastern edge of this landscape, defining the boundary between Colusa and Sutter counties and creating dramatic bends such as Ogden Bend and Girdner Bend. In the fertile lowlands of the Sacramento Valley, the town of Grimes serves as a central hub, connected by a network of rural roads like Grimes-Arbuckle Rd and Tule Rd. The area's agricultural character is evident through the complex irrigation systems including the Colusa Trough, Main Canal, and the Colusa-Basin-Drainage-Canal.

Private aviation is surprisingly prominent in this reach of the valley, with facilities like the Farnsworth Ranch Airstrip, Sanborn Airport, and Balsdon Airport dotting the countryside. Genealogists and local historians can locate the Grand Island Cem near Munson-Basin, while researchers of the river's geography will find named bars and sloughs such as Twentymile Bar and Byers Slough that provide clues to the region's historic water levels and land use.
