The Osceola Ditch, also known as the East Ditch, was built in 1889–1890 to convey water from Lehman Creek, Nevada to a hydraulic mine operation at Osceola. Extending for 18 mi (29 km), the ditch includes a 600 ft (180 m) tunnel as well as wooden flumes. The project also includes a rock dam and headgate on Stella Lake. The ditch's terminus at Osceola, Nevada became disused during the early 1900s and was destroyed entirely by a fire in the 1940s. Much of the East Ditch is included within Great Basin National Park.
