Significance
The Cochran Ditch, also known as the Cochrane Ditch,  is a testament to Reno’s evolving urban landscape and infrastructure. As one of the first major irrigation ditches, it represents the establishment of water systems crucial for meeting the growing agricultural needs of the burgeoning city during the 1860s-70s. The ditch encompasses Virginia Lake, a man-made recreational facility exemplifying New Deal projects in Nevada during the Great Depression of the 1930s. The Cochran Flume, located at the intersection of the ditch and Dry Creek, is currently threatened by potential removal, highlighting the ongoing urbanization of southern Reno and the reduction of the use of water for agriculture in the Truckee Meadows today. Furthermore, the Cochran Ditch holds a deep connection to the social history of Reno, illustrated by the organization of the United Parent-Teachers’ Association (United PTA) in 1927 and their fundraising initiatives during the 1930s-50s aimed at protecting children from drowning in the irrigation ditches.

Jury comments
The jury praised the quality of the research and the concise description of the resource and its defining features. The survey will make a great addition to the HALS collection in the Library of Congress. Your survey will be an invaluable reference for people studying the history of the ditch system and broader development of the City of Reno.
