Colorado Steamships

The Colorado River, flowing from the Rocky Mountains through the arid Southwest to the Gulf of California, was a challenging waterway—shallow, swift, and prone to sandbars, floods, and shifting channels. Despite these obstacles, steam-powered vessels played a vital role in its navigation from the mid-19th century until the early 20th century. Primarily operating on the lower Colorado River (from the Gulf of California upstream to areas near modern-day Nevada), steamboats transported military supplies, miners, settlers, and freight, fueling the development of Arizona, California, Nevada, and parts of Mexico. They were the most economical means of moving goods across the desert until railroads supplanted them.

Early Attempts and the Birth of Steam Navigation (1850–1854)

The need for reliable transport arose after the Mexican-American War (1846–1848), when the U.S. Army established Fort Yuma at the confluence of the Gila and Colorado Rivers to protect emigrants heading to California during the Gold Rush. Supplying the isolated fort overland from San Diego cost up to $500 per ton. River transport from the Gulf of California offered a cheaper alternative.

Initial efforts used schooners and barges. In 1850–1851, the schooner Invincible and longboats reached only partway upriver. Lieutenant George Derby recommended shallow-draft sternwheel steamboats.

The first successful steamboat was the small iron-hulled Uncle Sam, a 65-foot tug with a 20-horsepower engine, assembled at the river’s mouth in 1852 by Captain James Turnbull. It reached Fort Yuma in December 1852 but later proved unreliable and sank.

In 1853–1854, George Alonzo Johnson, partnering with Benjamin M. Hartshorne and others, formed George A. Johnson & Company. They brought parts for the sidewheeler General Jesup from San Francisco, assembling it at the river mouth. The General Jesup carried 50 tons of cargo to Fort Yuma in five days, reducing costs to $75 per ton and proving commercial viability.

Expansion and Exploration (1855–1860s)

Johnson’s company built wood yards staffed by Cocopah Indians and added vessels like the sternwheeler Colorado (1855, captained by Isaac Polhamus) and others. By the late 1850s, steamboats regularly serviced Fort Yuma and emerging mining camps.

Exploration pushed limits:

  • In 1857, Johnson took the General Jesup to El Dorado Canyon (near Las Vegas).
  • The U.S. Army’s 1857–1858 expedition, led by Lt. Joseph Christmas Ives, used the 54-foot iron steamboat Explorer (built in Philadelphia and reassembled on the river). It reached Black Canyon but struck a rock; Ives deemed further navigation impractical at low water. Johnson later bought the Explorer and converted it to a barge.

Mormon leader Brigham Young sought a sea-to-Utah route via the Colorado. In 1864–1866, Anson Call established Callville (near modern Lake Mead) as a potential port. Steamboats like the Esmeralda reached it in 1866.

Boom Years: Mining Rushes and Competition (1860s–1870s)

The 1862 Colorado River gold rush near La Paz (Arizona) and later discoveries in Eldorado Canyon and elsewhere created explosive demand. Ports like Ehrenberg, Hardyville, and Aubrey emerged. Steamboats hauled machinery, food, and ore, often towing barges for extra capacity.

George A. Johnson & Company dominated initially but faced rivals like Thomas Trueworthy’s Union Line in the 1860s. Competition ended when Johnson’s company absorbed opponents. In 1869, it reorganized as the Colorado Steam Navigation Company (C.S.N.Co.), expanding the fleet with vessels like Cocopah, Mohave, and larger ones like the 149-foot Mohave II (1876) and Gila.

Key captains included Isaac Polhamus (“Dean of the Colorado River”) and later Jack Mellon. Ocean steamships connected San Francisco to the river mouth at Port Isabel, feeding river traffic.

Peak and Decline (1870s–1900s)

The 1870s marked the peak, with scheduled services and luxurious boats offering passenger excursions. The C.S.N.Co. monopolized trade, profiting immensely from military contracts, mining,, and Mormon supplies.

Railroads spelled doom. The Southern Pacific reached Yuma in 1877, bridging the river. That year, Johnson and partners sold the C.S.N.Co. to Southern Pacific interests for a massive profit. Steamboats continued but focused on upper reaches and local freight.

Later vessels included the Cochan (1900, the last major sternwheeler) and Searchlight (1903–1909), hauling ore from Nevada mines.

End of an Era (1909–1916)

The 1909 completion of Laguna Dam (for irrigation) blocked navigation. Final operations involved limited freight and dam-related work. The last commercial steamboat, Searchlight, retired around 1916.

Attempts on the upper Colorado (e.g., Glen Canyon, Green River) were short-lived due to rapids and low water.

Legacy

For over 50 years, Colorado River steamboats connected isolated frontiers, enabling settlement and extraction in a harsh desert. They carried millions in gold, supplied forts and mines, and linked the Pacific to inland territories. Though overshadowed by railroads and dams, their era transformed the Southwest, leaving behind ghost towns, historic sites like Yuma Quartermaster Depot, and a romantic chapter in Western transportation history.

Needles – Colorado River Steamship Landing

Needles, California, located along the Colorado River, played a significant role in the history of steamship navigation in the American Southwest during the mid-19th to early 20th centuries. The Colorado River served as a vital transportation corridor, connecting mining camps, military outposts, and settlements in Arizona and California. Steamships were instrumental in delivering supplies, passengers, and mail, particularly during the region’s mining booms and the establishment of rail connections. This report explores the history of steamships in Needles, their operations, key vessels, and their impact on the region’s development, drawing on historical records and accounts of the Colorado Steam Navigation Company and related enterprises.

Historical Context

The Colorado River, stretching from the Gulf of California to the Green River in Wyoming, was a challenging but navigable waterway for steamships from 1852 to 1909. The discovery of gold in California in 1848 and subsequent mining booms in Arizona spurred westward expansion, increasing the demand for reliable transportation. Steamships became a lifeline for isolated settlements, as overland routes were slow and vulnerable to harsh conditions and conflicts with Indigenous groups. Needles, established as a key point along the river due to its proximity to rail connections and mining operations, emerged as a hub for steamship activity by the late 19th century.

The Rise of Steamship Operations

Steamship service on the Colorado River began in November 1852 with the launch of the Uncle Sam, a modest sternwheeler powered by mesquite wood. Capable of carrying 40 tons of supplies, it demonstrated the feasibility of steam navigation despite the river’s swift currents and shifting sandbars. The Colorado Steam Navigation Company (CSNC), formed in the 1860s, dominated steamship operations, operating a fleet of sternwheelers and sidewheelers designed for the river’s shallow draft, requiring as little as 30 inches of water. These vessels, ranging from 35 to 149 feet in length, could haul up to 236 tons of cargo and passengers.

Needles became a focal point for steamship activity in the 1880s, particularly after the Atlantic and Pacific Railroad reached the town in 1883, connecting it to the Southern Pacific Railroad. The construction of a wooden bridge across the Colorado River at Needles, completed in 1883, relied heavily on steamships for logistical support. The Mohave II, a prominent sternwheeler, towed barges and assisted in driving pilings for the bridge, despite challenges from the river’s strong currents. Steamships also supported subsequent bridge repairs after floods in 1884, 1886, and 1888, and the construction of a cantilever bridge at Mellen (near Needles) in 1889–1890.

Key Steamships Operating in Needles

Several steamships were associated with Needles, either as regular operators or through specific roles in supporting regional infrastructure:

  • Mohave II: A sternwheeler operated by the CSNC, the Mohave II was a workhorse of the Colorado River, active in the 1870s and 1880s. It played a critical role in supporting the construction of the railroad bridge at Needles by towing Barge No. 3, equipped with a pile driver, to secure pilings in the riverbed. In 1876, it carried a Sunday school group from Yuma, illustrating its role in community excursions.
  • Cochan: A sternwheeler operating around 1900, the Cochan made regular trips between Yuma and Needles, competing with the CSNC. Under the command of a former CSNC barge captain, it served mining camps and settlements, transporting supplies and passengers.
  • Searchlight: Launched in December 1902 at Needles, the Searchlight was the last sternwheeler built for the lower Colorado River. Operated by the Colorado River Transportation Company, it was 91 feet long and competed with the CSNC for trade to Quartette Landing and Searchlight, Nevada. Its launch marked the final phase of steamship construction in the region.
  • Gila: Active in the 1870s, the Gila was photographed at the Yuma Crossing in 1873, indicative of the type of sternwheelers that operated upriver to Needles. It supported mining operations and military outposts, carrying supplies and personnel.

These vessels were purpose-built for the Colorado River’s unique conditions, with stern paddlewheels that provided better maneuverability in heavy, sediment-laden waters compared to sidewheelers. Their shallow drafts allowed them to navigate sandbars, though they often required skilled pilots to avoid grounding.

Economic and Social Impact

Steamships were critical to the economic development of Needles and the surrounding region. They transported mining equipment, food, and other supplies to camps like Quartette Landing and Searchlight, supporting the region’s silver and gold mining booms. Passengers, including miners, settlers, and tourists, relied on steamships for travel to and from Needles, which served as a gateway to the interior. The CSNC’s steamships generated significant revenue, outpacing smaller river steamboats, and facilitated trade with Mexican ports and San Francisco.

Socially, steamships fostered community connections. Excursion trips, such as those by the Mohave II for Sunday school groups, provided recreational opportunities and strengthened regional ties. Steamships also carried mail, ensuring communication between remote settlements and the outside world. However, their operations were not without challenges, including competition from railroads and environmental obstacles like floods and low water levels.

Decline of Steamship Operations

The dominance of steamships in Needles began to wane in the late 19th century due to several factors:

  • Railroad Expansion: The completion of the Southern Pacific Railroad’s line to Needles in 1883 and the San Pedro, Los Angeles, and Salt Lake Railroad in 1905 shifted transportation from river to rail. Railroads offered faster, more reliable service, reducing the need for steamships.
  • Environmental Challenges: The Colorado River’s unpredictable flow, marked by seasonal floods and low water, made navigation difficult. The damming of the river, starting in 1905, further restricted long-distance travel, effectively ending steamship operations by 1909.
  • Competition: The Searchlight and other vessels faced competition from established operators like the CSNC and emerging rail networks, which cut into their profitability. By 1903, the Searchlight had already impacted CSNC’s trade, signaling the decline of steamship dominance.

By the early 20th century, steamships were relegated to occasional supply runs and excursions, with the Searchlight marking the end of new construction. The CSNC was absorbed by the Southern Pacific’s Western Development Company in 1877, and its operations dwindled as rail transport took over.

Legacy and Historical Significance

The steamships of Needles, California, left a lasting legacy in the development of the American Southwest. They enabled the growth of mining, trade, and settlement in a region where overland travel was arduous. The Mohave II, Cochan, and Searchlight symbolize the ingenuity of early steamship builders, who designed vessels capable of navigating one of the continent’s most challenging rivers. Their role in supporting the railroad bridge at Needles underscores their importance in integrating the region into national transportation networks.

Today, the history of these steamships is preserved in archival records, photographs, and historical accounts, such as those by Jerry MacMullen in Paddle-Wheel Days in California. The Colorado River’s steamship era, though brief, was a critical chapter in the story of Needles, reflecting the broader narrative of American expansion and technological adaptation. While the river is no longer navigable for steamships due to dams, the legacy of these vessels endures in the region’s cultural and economic heritage.

Conclusion

From the 1850s to the early 1900s, steamships were a cornerstone of transportation and economic activity in Needles, California. Operating under the Colorado Steam Navigation Company and other entities, vessels like the Mohave II, Cochan, and Searchlight connected Needles to the broader Southwest, supporting mining, rail construction, and community life. Their decline, driven by railroads and environmental changes, marked the end of an era, but their contributions to the region’s development remain significant. This report highlights the vital role of steamships in shaping Needles’ history and their enduring place in the story of the Colorado River.

Fort Mohave

Fort Mohave is a historic settlement located in the southwestern region of Mohave county, Arizona, United States. Nestled along the banks of the Colorado River near Beale’s Crossing, it has played a significant role in the development and growth of the American West. Over the centuries, this area has witnessed the presence of various indigenous tribes, Spanish explorers, American pioneers, and military forces, each leaving their mark on the region’s rich history.

The history of Fort Mohave dates back thousands of years, with evidence of human habitation found in archaeological sites within the surrounding area. The Mojave people, from whom the fort derived its name, were one of the prominent Native American tribes in the region. They lived along the Colorado River, engaging in agriculture, hunting, and trade with other indigenous groups.

The first recorded European contact in the area occurred in the 16th century when Spanish explorers, including Melchor Díaz and Francisco Garcés, ventured into present-day Arizona. They encountered the Mojave people and established a limited presence in the region through the establishment of missions and trade routes. However, it wasn’t until the early 19th century that significant European-American exploration and settlement occurred.

In 1826, trapper and explorer Jedediah Smith traversed the Colorado River, reaching the vicinity of Fort Mohave. His expedition paved the way for subsequent fur trappers and traders who ventured into the area in search of beaver pelts and new trade opportunities. This influx of fur trappers and mountain men led to increased interaction between Native American tribes and Euro-Americans, often resulting in conflicts and tensions.

The establishment of Fort Mohave came about as a direct response to these conflicts. In 1858, the U.S. Army constructed the fort on the east bank of the Colorado River, near the confluence of the Mohave and Hardy rivers. Initially known as Camp Colorado, its primary purpose was to protect American settlers and travelers on their journey to the California gold fields during the height of the Gold Rush.

Fort Mohave was strategically positioned along the major transportation route that linked the Atlantic and Pacific coasts, known as the Mojave Road. It served as a critical outpost for the U.S. Army during the American Civil War, as troops were deployed to protect the mail and telegraph lines and maintain control over the region.

The fort played a significant role in the military campaigns against Native American tribes, particularly the Mojave, Chemehuevi, and Navajo people, who were resisting the encroachment of settlers on their traditional lands. Numerous skirmishes and battles occurred in the area as tensions escalated between Native Americans and the expanding American population.

Following the conclusion of the Civil War, the fort gradually lost its military significance. In 1890, it was officially decommissioned, and the remaining structures were abandoned. However, the establishment of the Mohave Valley Irrigation Project in the early 20th century sparked a renewed interest in the region.

The irrigation project brought water to the arid lands surrounding Fort Mohave, facilitating the cultivation of crops and the establishment of farming communities. This development, coupled with the construction of the Davis Dam in the 1950s, which created Lake Mohave, transformed the economy and landscape of the area. The lake provided recreational opportunities, attracting tourists and supporting the growth of the local tourism industry.

The region continues to be influenced by its proximity to the Colorado River, offering a range of water-based activities such as boating, fishing, and water sports. The Fort Mojave Indian Reservation, located nearby, serves as a reminder of the area’s rich Native American heritage and provides a cultural center for the Mojave, Chemehuevi, and Navajo tribes.

Potholes California – Colorado River Steamship Landing

Potholes California is a former gold mining camp and ghost town located in Imperial County, California. The town is located on the western side of the Colorado River near the present day Laguna Dam. The location was first mined by Spanish Miners in 1871. These early workings and miners were lost during the Yuma War, 1850 – 1853.

Potholes California

From 1852 through 1909, Colorado Steamships ferried people and supplies up and down the Colorado River to mining camps and outposts. Following the discovery of gold in California, westward expansion of the United States was on the mind of most people seeking their fortune of livelihood. Wagon trains, horses and trains all brought people deep into the new county seeking their fortune. Lesser known is the role of the steamships, which brought supplies and people up the Colorado River from Baja California to the Green River in Wyoming.

There has been some little excitement in this part of the, country, caused by the discovery of new gold fields on the Rio Colorado, some fifteen miles above Fort Yuma, on the California side. I have just returned from the diggings, and find, after a careful examination of three days, that gold exists there in paying quantities, for many miles on both sides of the river. While at the newly discovered diggings, a considerable quantity of the oro has been taken out, considering the short time- they have been worked. From the claim of Messrs. Crandell & Co., $200 per day have been dug daily for the past six days. The manner of working is the same at at Jila city, heretofore described. The earth must be carried on the back a distance of one mile, and washed in a cradle. It is said that the total amount of the gold taken from Crandell & Co ‘s claim is about $4,000. – They have now constructed a cart-road from the mine to the river, and hereafter will be able to work at better advantage. Several other claims in the vicinity are paying from $10 to $16 per day; but most of the claims — for a good manner have been located — will not pay more than $2 per day to the hand, by the present process of working. If water could be obtained and sluice* used, from $40 to $100 per day might be washed. [We had news of these diggings in oar San Diego correspondence, published this morning, and the corroborating testimony of .our Fort Yuma correspondent is of much value, as confirmatory of the reports from San Diego. — Eds. Alta.]

I think, however, that the Gila mines are much more valuable, or will yield much more gold than these new diggings on the Colorado. Th« former have the advantage of being easily supplied with water, works for that purpose being now in progress.

Mining operations resumed again in 1859 with the rediscovery of gold. Placier mining operations proved successful in the 19th century. A steamship landing was established to ferry people and supplies to the location 15 miles up river from Yuma, Arizona.

The town of Potholes California was established during the building of the All American Canal and Laguna Dam.

Callville Nevada – Colorado River Steamship Landing

Callville Nevada is a ghost town and Colorado River Steamboat port, which is now submerged below the waters of Lake Mead. Bishop Anson Call founded and established a colony and warehouse on the Colorado River at the direction of the Mormon Leader Brigham Young. The settlement was located about 15 miles up river from the location of the future site of Hoover Damn.

Callville was established on December 2, 1864 when Anson Call arrived on a small bluff over looking the Colorado River in the Arizona Territory. The settlement was located at the conjunction of the later named Callville wash and the Colorado River.

The founding of the settlement was the churches effort to expand trade routes and European immigration into Utah from the south. The small portgage and landing site was one of several along the Colorado including St. Thomas, Saint Joseph, Overton, West Point, Mill Point ( Simonsville ) and Rioville.

During the Civil War, the army of the United States garrisoned at the site, to protect the Colorado River Steamboats and serve as a landing point for army. In December 1865, the outpost had the honor to become the county seat for Pah-Ute County, Arizona Territory. The station was short lived and transferred to St Thomas just two years later.

In 1869, the army garrison was removed. Following the war, Congress redrew some of the state boundaries and the settlement in the Arizona Territory is moved to Nevada. From 1866 to 1878, the landing at Callville was the High Water of Navigation for steamboat traffic on the Colorado River, which is 408 miles from Fort Yuma. The town was abandoned in June 1869 when the Steamships discontinued service to the site.

Today, the town lies in under 400 feet of water. However, the water levels in Lake Mead are at an all time low, and St. Thomas is currently above water.

“Take a suitable company, locate a road to the Colorado, explore the river, find a suitable place for a warehouse, build it, and form a settlement at or near the landing.” 

Brigham Young instructing Anson Call, 1864
