Ohio River Museum


On the deck of the W.P. Snyder at the 
    Ohio River Museum in Marietta, OHThe Ohio River Museum in Marietta is pleased to exhibit the extensive collection of the Sons & Daughters of Pioneer Rivermen. While you tour, discover the golden age of the steamboat and learn more about the ecology of the Ohio River system. The Ohio River Museum consists of three exhibit buildings, the first chronicling the origins and natural history of the Ohio River. The history of the steamboat on the Ohio River system is featured in the second building, along with a video presentation on river steamboats. The last building features displays about boat building, mussels in the Ohio River system, and tools and equipment from the steamboat era.

Outside the museum, on the Muskingum River, visitors can take an escorted tour of the W. P. SNYDER JR.-- the last intact steam-powered "pool-type" stern-wheeled towboat in the United States. After your museum visit, cruise the Ohio River on the Valley Gem, a working sternwheeler docked next door to the Ohio River Museum.

Other exhibits on the museum grounds include the pilothouse from the steamboat the TELL CITY, a full-scale reproduction of a flatboat from Ohio's early settlement period, and an 1800 dug-out canoe used as a ferry between Fort Harmer and Marietta's settlement. Also on site are a series of poles showing the heights of some of the worst floods to hit the area in its recorded history: the 1884 flood at 54.5 feet, the 1898 flood at 49.6 feet, the 1907 flood at 52.1 feet, the flood of 1913 at 60.3 feet, and the 1937 flood at 55 feet.

Colorful Characters of the River

April 2017 - October 2017

The river flows through our lives affecting us in unseen ways. There are a special few who have added to its charm and contributed to its legacy. These men and women have enriched our lives with their contributions. From river pirates, writers, musicians, and steamboat pilots, their legacies will live on forever in our souls.

Exhibited throughout the Ohio River Museum are a few highlights of the lives of these individuals. Some famous, some not well-known, all with special stories that help us appreciate the river even more.


Captain Posey

This exhibit focuses on Captain Cumberland W. Posey from Belpre, Ohio. In the late 19th and early 20th centuries Captain Posey, a black man, became one of Pittsburgh, PA's success stories, owning and running several towboats, a bank, and one of the first black baseball teams. Truely a man of industry and finance.
