The river continues through Whiteley Woods, passing Ibbotson dam before crossing under Oakbrook Road and back again to reach Nether Spurgear dam. Oak Brook flows southwards from the grounds of Tapton Hall to join the north bank, and Holme dam is close to the river as it enters Endcliffe Wood. Almost the entire length of the river from Fulwood Lane is part of the grade II listed Porter Valley Parks, a series of green spaces and parks created along the river valley between 1885 and 1938. of land in Endcliffe Woods, at the eastern end of the linear park, was bought by Sheffield Corporation in 1885, to create public walks and pleasure grounds, but they also had another motive. The river at the time was a serious health risk, as sewage from newly built houses to the north of the river was flowing into the channel. Once they owned the woods, they were able to build a sewer through it. They then asked William Goldring to create a public park in the woods, which included gravelled paths, flower beds, ornamental shrubberies, rustic bridges, seating and a refreshment room. Several dams were repurposed, with Endcliffe dam used for bathing, Holme dam for skating, and Nether Spurgear dam for wildfowl. In 1924, Sheffield's commitment to public spaces was recognised by Patrick Abercrombie in his Civic Survey, where he described the Porter Valley parks as "the finest example to be found in this country of a radial park strip, an elongated open space, leading from a built-up part of the city direct into the country."
