Damaged infrastructure impacts NID water supply

Severe damage to infrastructure owned by Pacific Gas & Electric (PG&E) at Lake Spaulding has effectively cut off water supplies to NID.

The situation will impact deliveries to all NID customers (raw water and treated water customers in Nevada and Placer counties) and have severe effects on lake levels and recreation opportunities this summer. Also, hydroelectric generation will be affected by the water restrictions.

The District is currently requesting voluntary 20 percent conservation by all customers. The lack of access to normal watershed runoff means the District will need to rely upon limited water storage to begin the irrigation season, which started on April 15. Conserving water will allow supplies to remain in Rollins and Scotts Flat reservoirs.
