The summer of 2007 was one of the wettest on record. Heavy rainfall in June led to high water levels in rivers as well as saturated ground. The prolonged rainfall continued into July. Two months' worth of rain fell in 14 hours on 20 July. This water couldn't infiltrate the saturated ground and remained as surface water, which entered both the River Severn and the River Avon quickly. The result was widespread flooding.
It is estimated that the flooding and water crisis cost the county of Gloucestershire £50 million.
