Canal system discussion set

Dale Johnson, a retired Pacific Gas and Electric Co. employee, and local historian Hank Meals will present an introduction to Nevada County’s historic canal system with emphasis on the Cascade Canal at 7 p.m. Monday at the Madelyn Helling Library in Nevada City.

Western Nevada County was once renowned as a center of invention and innovation for hydraulic engineering. Nineteenth century county engineers built the most extensive system of reservoirs and canals in the world. There were 824 miles of ditches in the county by 1880.

The original dams and ditches (or canals) were used for mining until a court decision in 1884 ended large-scale hydraulic mining. Some, like the South Yuba Canal, evolved into components of the present-day hydroelectric system and Nevada Irrigation District.

This event is sponsored by Save Our Historic Canals. For information call Meals at 470-0632 or e-mail to
