Hampstead Heath dam 'could save thousands from floods'

Help

Scientists studying one of North London's most famous parks say thousands of people could be at risk of flooding.

They estimate millions of gallons of water could flow off Hampstead Heath into the homes below and say new dams should be built to prevent a tragedy.

According to Met Office records, in 1975 almost seven inches of rain fell in just over two hours after a heatwave. One man died and nearby properties were flooded.

But, as Matt Cooke reports, residents and campaigners are not happy with the proposals.

Here, he talks to resident John Dollar, Michael Welbank of the City of London Corporation and Robert Sutherland Smith of the United Swimmers Association.
