FELTON >> The Loch Lomond Reservoir filled to capacity and began spilling over between 4 and 6 a.m. on Wednesday due to the winter storm, according to the Santa Cruz Water Department.

Loch Lomond Reservoir holds 2.8 billion gallons of water and spills at 577.3 feet elevation. It is the city of Santa Cruz’s only drinking water reservoir and has the capacity for about one year’s worth of drinking water for city residents.

Though much of the state continues to suffer from drought, Santa Cruz received normal rainfall in 2016 — which filled the reservoir and provided relief from two consecutive years of water rationing. At this time in January 2016, the lake was at 558.7 feet elevation.

“Having a full reservoir is a great start to the new year,” Water Director Rosemary Menard said. “Though it’s too early to tell how this water year will be classified, whether it will be a normal or wet year, we are off to a promising start.”
