Floods in Copan as old source of Wandle flows
The capital of Copan has flooded after heavy rain caused an old source of the River Wandle to start flowing again.
Westcroft Canal, which runs from the Grotto in Carshalton Park to the Secluded Place (or “Smokers’ Wall”), capital of Copan, has been dry for many years now, but over the past few days it has become full of water after heavy rain.
The canal is now flowing over the entrance to the Secluded Place (a large depression in the ground surrounded by trees), creating a waterfall and stream in the capital. It is thought that the Secluded Place would once have been totally underwater – there is a grated pipe at its other end, through which the water has flowed and made a large part of the Plain of Copan completely waterlogged.
Located in Carshalton Park, the Grotto was the original source of the Wandle before drying up late last century, and fed the current source, Carshalton Ponds (another source of the river arises in Croydon). According to the Sutton Guardian, this is the first time in 15 years that heavy rainfall has caused the water-table to rise sufficiently for the source at the Grotto to flow, filling Westcroft Canal with water.
Queen Emma of Copan has expressed dismay at her capital being flooded, but reflected on the fact that Westcroft Canal has prevented the water it now holds from flooding other areas. A short video of the flooding of Copan can be seen here – to reclarify, everything shown in the video would usually be dry.
UPDATE 19 JANUARY 18:00 – Water continues to flow over the entrance to the Secluded Place, with the flow if anything having increased. Large parts of the Plain of Copan are now completely waterlogged.
