In order to complete our flood investigation reports and enable us to effectively prioritise our action plans, we need to understand which areas have been affected by flooding. You can help by reporting current, recent or historic flood incidents on the Severe Weather Information Management (SWIM) system. If you are reporting an incident where a) five or more properties have flooded internally or b) at least one property has flooded internally that has also flooded internally within the last five years, a Section 19 Flood Investigation Report will need to be published by Cornwall Council.

N.B. Do not use the SWIM form below to report an emergency situation or to alert us to current flooding requiring an immediate response.

Report a flood incident on the SWIM portal

Additional emergency contacts and information is available on the Cornwall Community Flood Forum website.
