Rewetting Wilden Marsh
A misconceived flood alleviation project carried out during the 1970s, resulted in dredging of the River Stour and the removal of its historic weir at Wilden.
The project caused severe hydrological problems. As the marsh dried out, important and rare wetland flora and fauna struggled to survive. The whole wetland ecosystem became increasingly endangered.
To help rewet the marsh, the Environment Agency installed two new rock weirs during 2010: one mid marsh and another at the southern end of the south marsh. The weirs were designed to lift the Stour water level by 1.5 metres. The new south weir failed and two years later it was reinforced with larger rocks.
Rewetting of the marsh is critical to its regeneration, its future health, and the continued success of its rare wetland flora and fauna.
