On the heels of the driest ever start to the year in California, Gov. Gavin Newsom on Monday issued a sweeping executive order calling on local water suppliers to implement more aggressive conservation measures as reservoirs dwindle and residents backslide in their efforts to cut back.

Specifically, the order requires that urban water suppliers activate “Level 2″ of their locally customized contingency plans, meaning they must prepare for a shortage of up to 20%.
