The south Placer County city receives 75 percent (32,000 acre feet) of its water from Folsom Reservoir. The U.S. Bureau of Reclamation, which manages Folsom Reservoir, says lower-than-expected Sierra snowmelt, an already low reservoir water level and competing needs necessitates reducing Roseville's water allocation.
Roseville also receives 10,000 acre feet of water from the Placer County Water Agency and 400 acre feet in groundwater. But with water demand expected to be 35,600 acre feet this year, with all water resources combined, there will be less water available than needed.
Residents and business are asked to reduce water consumption by 10 percent. The city is increasing water waste patrols; banning washing driveways, sidewalks, buildings, parking lots and streets unless public health requires it; and asking restaurants to not serve water, unless customers request it.
Letters will be mailed to all Roseville households and businesses in May to inform of the drought stage requirements.
There is no word if other municipalities which rely on Folsom Reservoir water will be similarly affected.
