Port Isabel was a seaport established in 1865 during the American Civil War in Sonora, Mexico near the mouth of the Colorado River on the Sea of Cortez to support the increased river traffic caused by the gold rush that began in 1862 on the Colorado River and the Yuma Quartermaster Depot newly established in 1864 to support the Army posts in the Arizona Military District.
