Capacity was an American schooner that arrived in San Francisco on January 9, 1852. [1] The Capacity under Captain Driscoll, subsequently was hired by Captain James Turnbull to carry a cargo of U. S. Army supplies for Fort Yuma. It would also carry the engine, boiler and wood to assemble the side-wheel paddle steamer tug, Uncle Sam to the Colorado River Delta. The Uncle Sam would be the first of many steamboats on the Colorado River.
After arriving in early September, the Capacity then had to wait longer than expected, over two months, in the anchorage in the estuary of the river until the Uncle Sam was built and launched in mid-November and then again waited four more months to empty its hold of the Army supplies. The anchorage was a trial for a ship anchored in that location, subject to extreme tides that left the ship stranded at low tide and struck by a 4 to 6 foot tidal bore when the tide came back in twice a day. The long wait was due to the limited 35 ton cargo capacity and the weakness of the 20hp engine of the tug when pitted against the strong down stream current of the Colorado, that made a round trip to and from its destination at Fort Yuma take 12 days each. The Capacity was successfully unloaded and left the river. [2] The subsequent fate of the Capacity is unknown.

Port Isabel was a seaport established on Port Isabel Slough in 1865 during the American Civil War in Sonora, Mexico in the mouth of the Colorado River on the Gulf of California. It was founded 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. The slough was discovered in 1865 by the Captain W. H. Pierson of the schooner Isabel, that first used the slough to transfer its cargo to steamboats safe from the tidal bore of the Colorado River. Shortly afterward Port Isabel was established 3 miles up the slough and replaced Robinson's Landing as the place where cargo was unloaded in the river from seagoing craft on to flat bottomed steamboats of the Colorado River and carried up to Fort Yuma and points further north on the river.

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. 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.
