The restoration of Calver weir, UK

Calver weir lies at the centre of a stretch of the River Derwent in North Derbyshire, UK, which is locally renowned for its attractive natural appeal. The weir creates the high-level upstream river and the resulting wetlands. The weir was built in the eighteenth century to provide water to power a mill. In the twentieth century some repairs were carried out but these subsequently failed, leaving the weir in a dangerous condition. A company, called the Calver Weir Restoration Project, was set up to restore the weir. This paper describes the weir, the problems encountered, solutions and the reconstruction works and amenities for water voles around the side of the fish pass.
