California’s water supply got cut again Wednesday, with the federal government reducing allocations to cities and farms as the drought intensified.

The U.S. Bureau of Reclamation announced that municipal water agencies that rely on the Central Valley Project will have this year’s allocations slashed from 55% down to 25% — a level not seen since the drought of 2015.

That could put additional pressure on the municipalities around greater Sacramento that depend on supplies from Folsom Lake, whose water levels have sunk dramatically this spring. The reservoir is at 46% of its usual capacity for late May.
