Waterbody description

WFD 2016 overall is Poor, failing for phosphate from probable sewage point source pollution. Rising in Idstone and Ashbury, two streams flow northerly towards Stainswick, winding through agricultural fields before passing the Great Western railway to reach east Shrivenham. It flows to the south of Watchfield and joins the river Cole at Bower Bridge. The geology is chalk in the upper reaches, flowing over bands of sandstone and clay before reaching limestone before its confluence.
