Fort Mohave on the Arizona side of the Colorado River was built for operations against the Mohave and was the second American military post established on the river after Fort Yuma. Eventually advantages in weaponry and tactics brought the Mohave and their allies to surrender. After the signing of a peace treaty in 1859, the Mohave no longer opposed the United States through warfare. The peace also ended a long guerrilla war between the Mohave and the Maricopa of south central Arizona.

The shallow draft paddle steamers were found to be the most economical way to ship goods between the Pacific Ocean ports and settlements and mines along the lower river, putting in at landings in Sonora state, Baja California Territory, California state, Arizona Territory, New Mexico Territory, and Nevada state. 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.

Fort Romualdo Pacheco also called Fuerte de Laguna Chapala was a Mexican fort built in 1825 and was abandoned a year later in 1826. The fort was 100 feet square with thick stone and adobe walls. The fort was built by Lieutenant Alfrez Jose Antonio Romualdo Pacheco Sr. in response to the attacked on travelers on the route made by Juan Bautista de Anza's expedition in 1774 from Sonora to Alta California. The fort was built after Fernando Rivera y Moncada, many of his soldiers, Francisco Garcés and his local missionaries, were killed at Mission San Pedro y San Pablo de Bicuñer in that is called the Yuma Revolt or Yuma Massacre on July 18, 1781. The attack was by the Apache Quechan Indians. The Yuma Massacre closed the overland transportation between northern Mexico and Alta California for 50 years. This halted the immigration of Mexicans to Alta California. Lieutenant Pacheco with soldiers and cavalry from the Presidio de San Diego built the fort in later 1825 and early 1826. The fort was built just north of the New River and south of the Bull Head Slough in what is now Imperial, California. The Fort was only used for a few months in 1826. Pacheco returned to San Diego and put Ignacio Delgado in charge of the Fort. On April 26, 1826, the San Sebastian Kumeyaay Indians attacked the fort. Pacheco had heard about rumors of the attack and arrived during the attack with reinforcements from San Diego. Pacheco and his 25 lancers fought off the attack. In the battle, three soldiers were killed and three injured. In the battle, 28 Indians were killed. But, now the fort was surrounded by many Kumeyaay and Quechan warriors. Vastly outnumbered the Fort was abandoned and all returned to San Diego. Archeologists did digs at the site in 1958 before Imperial Valley College Museum removed the remains.
