Natural Flood Management Interventions on Crompton Moor

The works currently being undertaken are part of an initiative to introduce Natural Flood Management measures to upland areas to help reduce the risk of flooding to communities downstream.

The measures being installed in the adjacent watercourse, the Old Brook, are called engineered log jams or leaky dams. The log jams are designed to hold water back during and following rainfall events and release it slowly so that we can control the rate of flow downstream in the River Beal.  This can help to reduce the risk of flooding to communities adjacent to the river Beal, such as Crompton, New Hey and Milnrow.

Allowing the water to back up will not only provide flood management benefits but it will also create new habitat space for plants, insects and amphibians and will help to support the establishment of sphagnum moss which is key to the restoration of the peatland bog.

The leaky dams are being constructed from trees being felled from the adjacent woodland plantation. The trees being removed will help to allow more light into the woodland which will encourage a greater diversity of ground floor shrubs and plants to establish which is good for wildlife.  Permission has been granted from both Oldham Council and the Forestry Commission to remove these trees.  Working with Friends of Crompton Moor, City of Trees have established which trees are most suitable for felling to ensure that protected wildlife species are not disturbed.
