Our Sheffield A to Z

D is for Damflask Reservoir and Agden Reservoir

Damflask Reservoir, located in the Loxley Valley, covers 47 hectares with a capacity of 4,250.9 million litres and a maximum depth of 27 metres. Completed in 1896, it was built by the Sheffield Waterworks Company as one of several reservoirs in the Bradfield area to provide water for Sheffield's population and industries. The reservoir was named after Damflask village, which was destroyed in the Great Sheffield Flood of 1864. Today, Yorkshire Water owns the reservoir and has opened it for recreational activities, including rowing, sailing, and fishing. In 2002, access to surrounding woodlands was expanded under the Countryside and Rights of Way Act 2000. Additionally, a 2015 project improved accessibility for disabled visitors.

Agden Reservoir covers 25 hectares with a capacity of 559 million gallons. Completed in 1869, it was built to support Sheffield's steel industry, collecting water from the surrounding moorlands. The reservoir is fed by Hobson Moss Dike and Emlin Dike and is largely surrounded by coniferous woodland. However, Sheffield City Council is replanting broadleaved trees to enhance wildlife habitats and aesthetic appeal. A popular walking route circles the reservoir, starting in Low Bradfield and passing through Agden Bog, a protected wetland. The area features remnants of old farm dwellings, some demolished by water authorities to prevent potential water contamination. Notable structures include the former Keeper's Cottage, now a private home, and Agden Lodge, built in 1870 for Samuel Fox, which remains privately owned.
