Missing watercourse- small stream which appears on some maps as part of the River Ray. The boundary between Chiseldon and South Swindon Parishes follows the stream at the northern edge of Burderop Wood south of the M4. North of the M4 it takes a path through Nightingale Farm, forms a wet woodland west of Broome Manor Lane, and ultimately flows into Coate Water. I'm unsure of what path it takes beyond Burderop Wood south of the M4.
