Lack of rainfall prompts low water situation in Upper Thames Valley watershed

As London enters its third heat warning of the year, the Upper Thames Valley watershed is facing a low water situation due to a lack of rainfall. The lack of rain has prompted a level one low water situation with the Upper Thames River Conservation Authority. Between June 15 and July 15, the watershed only received 17mm of rain — a mere 22 per cent of what is considered normal precipitation levels for that time of year.
