GRASS VALLEY, Calif. March 1, 2017 – NID expects no impacts to their customers after a major canal collapsed on February 10. The South Yuba Canal delivers water for 12,900 customers in the Grass Valley and Nevada City area, according to supporting documents for today’s emergency declaration.
In a phone call to YubaNet, NID spokesperson Susan Holt confirmed the district is not expecting any impacts on the water delivery to their customers. NID will work in conjunction with PG&E, the owner of the canal, to assess and repair the damage.
