Exmoor National Park Authority

A practical task building leaky dams at ENPA's Driver Farm, near Challacombe.

A leaky dam is a natural flood management method, which involves placing branches and twigs across small waterways between a framework of upright posts. These dams help slow the rush of water off the moorland in times of heavy rain, meaning less soil is eroded from the moor.

We will be concentrating on constructing a series of these dams along a deep drainage ditch dug orignally in John Knight's era to drain the moor as part of his plans to turn barren moorland into productive agricultural land.  

Please note: Access to the dam building site involves a 1km walk across uneven and sloping ground, carrying hand tools and equipment.

The entrance to the farm is off the B3358 at Driver Cottage between Simonsbath and Challacombe. The farm drive has a narrow entrance, on the right hand side of the road as you head towards Challacombe from Simonsbath, between a little stone bridge and the cottage. Go up the farm drive and please park where directed. Please close the gate after you as there may be stock grazing near-by.
