The Wyming Brook is a river in the City of Sheffield, England. Its source is the Redmires Reservoirs near the Hallam Moors. It flows in a north-easterly direction for over 0.6 miles (1 km) down quite steep terrain into an underground chamber where it joins the Rivelin tunnel before it flows into the lower of the Rivelin Dams. The river flows almost its entire length within the Wyming Brook Nature Reserve, a Site of Special Scientific Interest which is managed by the Wildlife Trust for Sheffield and Rotherham.

Rivelin Dams are a pair of water storage reservoirs situated in the upper part of the Rivelin Valley, 5 miles (8 km) west of Sheffield in South Yorkshire, England. The dams are owned by Yorkshire Water and provide water to 319,000 people as well as compensation water for the River Rivelin. They are named Upper and Lower and fall just within the eastern boundary of the Peak District.
