Porter Brook

The Porter Brook is a river in the City of Sheffield, England descending over 1,000 feet (300 m) from its source among the sedge grass on Burbage moor behind a small farm on Hangram just inside the Peak District National Park in the west of the city at Clough Hollow, near the village of Ringinglow.Coordinates: 53°21′19″N 1°33′56″W / 53.3552°N 1.5655°W / 53.3552; -1.5655 Porter Brook derives its name from its brownish colour, similar to the colour of Porter, a brownish discolouration obtained as it passes over iron-ore deposits on its course from the source.

From here it flows eastward through Porter Clough through Mayfield Valley to the first of the remaining mill dams. Beyond Forge Dam the brook makes its way through Endcliffe Park to Hunter's Bar, before running between Ecclesall Road and Sheffield General Cemetery, past the former Wards brewery. The final section of the river from Pear Street, location of Sharrow Forge (No. 15), is now built over running through culverts beneath the intersection of London Road and the Inner Ring Road. It meets the similarly subterranean River Sheaf beneath Sheffield Midland Station.
