Its source is on Gratton Moor and after passing below Youlgreave it joins the River Lathkill at Alport. Less than 4 miles in length, its waters are very clear due to the limestone rock over which it flows, and its width has been enhanced by a number of weirs which also encourage white-throated dippers to breed in the ponds created. The river is owned and managed by the Haddon Estate and is home to brown trout and white-clawed crayfish. The valley is known as Bradford Dale, and the Limestone Way long distance footpath passes through it.
