Hundreds of natural dams help prevent flooding on Levels

Two years after the devastating winter floods on the Somerset Levels, further efforts are being put in place to prevent further flooding disasters from happening again.

Hundreds of natural dams are being built across the streams that flow down the hills above the levels.

This little stream is part of a big problem for the Somerset Levels. The 'Sherford stream', as it is known, begins on Blagdon Hill and flows down to the Tone in Taunton.

There are scores of streams like this in the hills above the levels and when it rains the water flows faster.

The natural dams are being built to hold the water back in times of flood.

These woody, or leaky dams are designed to mimic the effect of fallen trees. They're being created as part of the Hills to Levels project which, in part, aims to make the Levels more resiliant to flooding.

The dams work when water levels are highest, forcing floodwater to spread over neighbouring land, into ponds that build behind.

But fish and gravel can still move along the river.

Elsewhere trees are being planted and farming techniques are being reviewed to encourage water to soak in, rather than run off fields.

It's a welcome start to tackling unwelcome flooding.
