Dry conditions in West Virginia's mountains have at least one county worried about drinking water supplies.

The Pocahontas County Public Service District has imposed an emergency water rationing plan because of falling water levels.

The order affects customers in the communities of Durbin, Frank and Bartow.

PSD spokeswoman Cindy Barkley says customers are being urged to conserve water by not washing their vehicles and curtailing other water uses.

Officials say the state's higher elevations need three to five inches of rain to replenish local water supplies and to get springs and streams flowing again.

Rain is forecast for the state on Friday, and the weather service says the mountains could receive up to an inch of rain by Saturday.
