The small coastal town of Lynmouth became known throughout the world for the disaster which struck in August 1952. On the night of the 15th, after continuous rain throughout the day, the East and West Lyn Rivers rose suddenly and filled with the waters from their Exmoor catchment. Large boulders and rocks were carried in the flow towards the village, destroying houses, roads and bridges. Many lost their lives during that dark and terrifying night. The whole of Exmoor was affected and considerable damage was caused on the Barle, Exe, Heddon and Bray but the worst effects were at Lynmouth. This is because the water draining from most of the northern side of Exmoor ends up in the East and West Lyn Rivers, which join at Lynmouth. Hundreds of thousands of years ago these rivers used to run to the sea much further to the west but during the Ice Age the side of their valley was eroded by the sea and, as a result, they now fall to the sea along a much shorter and steeper course. As a result the waters descending on Lynmouth are particularly fast and erosive. Thirty four people died in this disaster.
