Essex & Suffolk Water, who own and manage Abberton Reservoir, have noticed a rapid reduction in the abundance of submerged plant life in the reservoir close to where Layer Brook flows in. Investigations have so far failed to explain the loss of plant life but have identified an increased build-up of sediment from Layer Brook.
The Topsoil project aims to bring greater certainty to the sources and effects of sedimentation in the reservoir.
