: This photograph, taken in the 1960s, documents Rokeby Lock #8 on the Muskingum River. It measures 2.75" x 2.75" (6.99 x 6.99 cm). The Muskingum River begins at the confluence of the Walhonding and Tuscarawas rivers in Coshocton, Ohio and flows south to the Ohio River at Marietta. Ten locks constructed along the river allow boats to travel the 112-mile distance of the Muskingum River. In 2001, the American Society of Civil Engineers named the Muskingum River locks a National Historic Civil Engineering Landmark. Locks allow boats to navigate the different elevations of the natural terrain. The structure consisted of two gated areas in the canal. When a boat entered the lock, a gate closed behind it and the water level was raised, floating the boat to the higher elevation. When the water level inside the lock equaled that on the other side of the gate, the boat was released. View on Ohio Memory.
