Cound Brook is a tributary of the River Severn running from the All Stretton area through Longnor and Condover and emptying into the Severn near Cound. Longnor lies in the middle section of Cound Brook. Having rainwater runoff from the Stretton Hills join it, the brook widens, passing to the east of Leebotwood and west of Longnor and the Medieval deer park there. Continuing east of Dorrington village, it changes direction to east at Stapleton. The flow can vary from slow and sluggish in a dry summer to a torrent in winter or spring.
