Museum of Missouri River History
Backstory and Context
This massive vessel, at a length of 268' 11-1/2", housed a standard operating crew of 52, with quarters available for 58 men. The Lewis dredge could dig to a depth of 20 feet at an average speed of 150-200 feet per hour, all powered by the 25-foot steam-propelled paddle wheels. With all three steam engines running, the dredge burned up to 6,000 gallons of oil in a day.
The Babcock and Wilcox marine boilers could produce up to 40,000 pounds of steam or more per hour when dredging. The triple expansion engine that drives the pump turbine is rated at 1,300 hp. The dredge was pulled forward by the two deck gypsies and not propelled by the paddlewheels when dredging.
In 1976, the Captain Meriwether Lewis was given to the Nebraska State Historical Society and moved to Brownville one year later. It was dry-berthed along the Missouri River where it remains today.
The Meriwether Lewis was designated a National Historic Landmark in 1989. Today, theCaptain Meriwether Lewis houses the Museum of Missouri River History where exhibits from Native American history to exploration and westward expansion can be seen. Visitors can also learn about the vessel and its role in improving navigation on the Missouri River."1
