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.
The proposed emergency declaration will allow NID to rapidly begin repairs and give the district the ability to take appropriate measures like conservation, if needs be.
NID has been receiving calls from customers worried about possible shortages. Holt said “no one is not going to get water,” reassuring locals eager to plant their vegetable gardens or landscaping.
