California’s mighty rivers served as the state’s early superhighways. Riverboats transported countless tons of supplies, workers, and settlers from the coast to inland gold rush colonies and everywhere in between. Majestic sidewheelers and sternwheelers burning coal, wood, and oil plied the waterways of the delta, as well as the Sacramento, San Joaquin, and Napa Rivers, and the lesser-known routes of the Sonoma and Petaluma. Starting with the Sitka in 1847, boats such as the Captain Weber, Jacinto, Fort Sutter, T.C. Walker, and J.R. McDonald ruled the rivers, visiting such ports as Courtland, Stockton, Sacramento, San Francisco, Marysville, Firebaugh, Yuba City, and Rio Vista.
