 Calf Hey Brook is joined by another stream occasionally termed Roddlesworth - which rises beneath Cartridge Hill and runs past the ruins of "Hollinshead Hall" - beneath "Slipper Lowe".From there, it follows a northerly course through Roddlesworth Plantations, around the two reservoirs fed by the river and past Red Lees.The river continues through the Stanworth Valley in Livesey, where it is met by Stockclough Brook, and under the M65 motorway and Leeds & Liverpool Canal.
