1. Sullivan & Kelly Ditch Marker

Inscription. Constructed in 1872 by James D. O’Sullivan and Patrick J. Kelly, the historic Sullivan & Kelly Ditch was built to irrigate their ranches located in the northeast Truckee Meadows. Enlarged in 1877, the ditch originally measured three-and-one half miles long, six feet wide, and four feet deep. A low dam and flume diverted water from the Truckee River into the ditch. This dam spanned the north channel of the river by Belle (Wingfield) Isle, west of the Chestnut (Arlington) Street Bridge. As the City grew, the open ditch proved hazardous, and in 1940 it was modified and buried as a concrete conduit. In 1956, when another nearby ditch closed, additional improvements were made to increase water capacity. New installations included an intake valve, outlet structure, reinforced concrete pipe, manholes, and drain pipes. The last record of water diversion was in 1971 with only 500 yards of the ditch still in use. In 2003 the dam and diversion structure were removed as part of the river channel modification for the Truckee River Whitewater Park.
