Essex County Council are working with the Environment Agency to install a series of leaky wood debris dams upstream of Old Hall Pond in Thorndon Country Park, Essex.  This aims to reduce the flood peaks downstream in West Horndon, a village prone to flooding. Flooding in West Horndon last occurred in 2012. It is also hoped that the dams will slow the transport of sediment into Old Hall Pond, which may affect the fish stocks, and so we are measuring turbidity levels in Old Hall Pond pre- and post- installation of the debris dams.
