The newest reading of California’s critical mountain snow pack is showing that the state currently has zero-percent of its normal snow levels. The snow reading is the lowest ever taken at this point of the year.

A warm, dry winter means that little snow fell in the higher elevations of the Sierra Nevada.

The snow pack is critical to replenishing California’s surface water supply.

Maury Roos with the California Department of Water Resources says the measurement has never come in this low.

“I think the previous low year would be back in the drought of 1977, and at least then we had 25-percent. This year we have the lowest snow pack ever measured,” Roos said.

Roos says reservoir storage statewide is about 58-percent of normal and unlikely to increase because there won’t be any more snow melt this season.
