Sheaf & Porter Rivers Trust The Sheaf & Porter Rivers Trust is a voluntary organisation set up on 15 May 2019, to promote public awareness of the two urban rivers and their gradual regeneration. The trust is one of several organisations which promote remediation of these rivers, including Sheffield Corporation. The trust believe that remedial action on the lower Sheaf and Porter would improve biodiversity, as well as the health and wellbeing of the increasing population of the inner city. At the time of its formation, there were significant re-development projects taking place on the lower Porter, which gave scope to improve the level of daylight on the river and to create public spaces. A retail outlet has been persuaded not to replace the culvert roof where their car park had collapsed into the river, and the Trust are working with the Environment Agency to ensure that the exposed river gets re-naturalised. They have also negotiated with the BBC, where the river runs beneath the car park. It included a section where the exposed river was totally overgrown, to the extent that the owners did not realise there was a river. As of May 2022, the intention is to cut back the growth and so let light into the river. The Trust are also promoting the creation of a larger park where the combined waters of the Porter and Sheaf flow into the Don. The final culvert through which they run is decaying, and the trust would like to see it removed. They would also like to see light wells added throughout the rest of the culverts, to enable wildlife to pass through them to reach the upper rivers, and believe that redevelopment as part of the HS2 high speed rail link could be the catalyst for that to take place. They are also seeking a continuous path along the river bank, joining the current disconnected sections. Popular culture The river is one of several which inspired the song "Wickerman" by Pulp. The Sheffield morris dance group, Five Rivers Morris, who take their name from the city's waterways, have a dance called 'Porter' after the Porter Brook. The Porter Brook featured heavily in a 2016 BBC Radio 4 documentary entitled "A River of Steel", produced by sound recordist Chris Watson, ex-member of Caberet Voltaire. The programme included discussion of the recently completed Porter Brook daylighting scheme, which
