On 30 Jan 1607 around midday the Bristol Channel suffered from unexpectedly high floodings that broke the coastal defences in several places devastings significant areas of South-Wales and Somerset. It is estimated that 2,000 or more people were drowned, houses and villages were swept away, an estimated 200 square miles (51,800 ha) of farmland inundated, and livestock destroyed, wrecking the local economy along the coasts of the Bristol Channel and Severn Estuary. The coast of Devon and the Somerset Levels as far inland as Glastonbury Tor, 14 miles (23 km) from the coast, were also affected. The sea wall at Burnham-on-Sea [Map] gave way, and the water flowed over the low-lying levels and moors.
