Colusa County in the heart of the Sacramento River Valley is in the north Central Interior of California.  Bordered to the west by the Coastal Mountain Range and to our east the Sacramento River. Our location offers a picturesque agricultural landscape still mostly untouched by massive city development. It is one of the few remaining oases of uncluttered western frontier that remain in California.
            Like much of California, the topography of Colusa County is varied. The 7,000 foot peak of Snow Mountain sits on the County's western edge in the Mendocino National Forest. Traveling down from the mountain, one passes world famous wild flowers in the range lands which cover much of the County's western third. About 10 miles west of Interstate-5, these foothills ease into the rich, fertile soils of the Sacramento Valley. The Sacramento River, with a watershed covering much of Upstate California’s interior, washes the county's eastern boundary.
             Colusa County’s location on Interstate-5 and State Highway 20, the main north/south & east/west thoroughfare running across her centerline, offer business and industry the ideal site for development and expansion.  With our close proximity to the State Capitol and the San Francisco Bay Area we offer rural appeal with major city amenities near by.
