The 1814 Perth flood was caused by the River Tay, Scotland's longest river, rising to 7 metres (23 feet 0 inches) above its normal level. It occurred on 12 February 1814, in Perth, Scotland.[1] It was partly caused by ice jams beneath Perth Bridge, which was built 43 years earlier.[2] The river's height matched that of a flood in 1774.[3]
Perth's 1993 flood came close to breaking the record for the height of the Tay's waters, but it peaked at 6.48 m (21.3 ft).[4][5]
