Steamboats on the Colorado River operated from the river mouth at the Colorado River Delta on the Gulf of California in Mexico, up to the Virgin River on the Lower Colorado River Valley in the Southwestern United States from 1852 until 1909, when the construction of the Laguna Dam was completed.

They remained the primary means of transportation of freight until the advent of the more economical railroads began cutting away at their business from 1878 when the first line entered Arizona Territory.
