encompassing the following
London Wildlife Trust have undertaken meander reconnection works at Crane Meadows Nature Reserve in Cranford, Hounslow.
The meanders were cut off from the river over 100 years ago when the river was subject to heavy modifications. The London Borough of Hounslow and the Environment Agency had previously reconnected three meanders at the site. LWT's input now brings this total to five.
In addition to the meander connections a backwater area was created to improve the river's resilience to pollution events and to enhance habitat for juvenile coarse fish.
Aims of this Project
1. To increase morphological and flow diversity in the river channel leading to better quality habitat for macrophytes and benthic invertebrates and improved habitats for fish.
2. To decrease flow conveyance and increase water storage capacity, contributing to the rivers hydrological response time being reduced during periods of high flows.
3. To provide new back water areas for aquatic organisms to shelter from the main flow of the river during times of disturbance, including pollution events.
4. To increase public awareness and appreciation of the issues affecting the Crane Catchment and the techniques used to solve them via a volunteer engagement programme.
A gravel riffle will be placed just downstream of the meander inflow to ensure all water flows through the meander when river levels are low.
The bund blocking the inflow of water to the meander will be removed.
