Lake Tahoe has almost filled to the brim, promising years of consistent water supply to the Reno area.
Truckee Meadows Water Authority Senior Hydrologist Bill Hauck says Tahoe's level has risen more than seven feet in less than a year.
"Tahoe will have the single largest rise in terms of gains in storage in one water year in recorded history," says Hauck.
During the drought, the agency had to release water from other reservoirs, including Donner Lake, to keep a steady supply to its customers.
Hauck says a full Lake Tahoe guarantees Reno will have two to three years of normal water supply.
Water regulators have already begun a precautionary draw-down of Tahoe in preparation for more storms and spring snow melt.
The last measurement of the Tahoe Basin's snow pack showed it was 233 percent of normal.
A new snow pack report for the Sierra will come out Wednesday.
