Reservoirs are dangerous and the government advises against swimming in them.
According to the National Water Safety Forum, more than half of deaths from drowning happen in inland waters, such as rivers, lakes and reservoirs.
The risks of unauthorised swimming in reservoirs are not widely known and unfortunately there have been several serious accidents and fatalities at UK reservoirs this summer.
A reservoir is nearly always man made and, because of their purpose, they carry a set of specific dangers in addition to those which apply to other outdoor settings.
English and Welsh water companies want to keep everyone safe. Please follow this simple rule when visiting their reservoirs:
Stay out of the water, no matter how strong a swimmer you are.
