The rainy season is nearly over, there’s been no “March miracle” and the possibility of parched lawns and fallowed farm fields is growing.

State and federal officials issued remarkably bleak warnings Tuesday about California’s summer water supplies, telling farmers and others to gear up for potential shortages.

The Department of Water Resources, in a rare turnabout, actually lowered its forecast of the deliveries it expects to make to the cities and farms that belong to the State Water Project. In its new forecast, the agency said its customers can expect just 5% of contracted supplies. In December the expected allocation was set at 10%.
