Dry spell affects water levels at some reservoirs
The dry weather has caused a fall in water levels at some of Britain's reservoirs
Bristol Water bosses say the Chew Valley lake reservoir in Somerset, which supplies water to about half a million homes, is normally full at this time of year, but is currently only at 80% of its capacity.
Water from the River Severn is now being used to supplement supplies.
