There were 193 accidental water-related fatalities last year, with 11 occurring in the south east of the country.

One, recorded at Sunbury Lock in October, involved a 68 year old rower who died after his boat capsized.

Now, voluntary network, National Water Safety Forum, is urging river users to join its Respect the Water campaign.

This means being aware of the risks, like cold water shock, and by knowing how to help yourself and others in an emergency.
