River Ray, Grendon Wood

Looking east, this stream, which flows east to west through Grendon Wood, is the River Ray. The source of the river is a spring on the northern slope of Grange Hill near Shipton Lee, SP73982127 4km to the east. From Grendon Wood, the river flows south-west through farmland and joins the River Cherwell at Islip Weir about 22km away, which itself joins the River Thames (or Isis) in Oxford.

Here is the river further west near the village of Blackthorn on the Buckinghamshire-Oxfordshire border, SP6320 : Flooded River Ray. The upper River Ray area is one of the last strongholds for threatened wading birds and traditional floodplain meadows in England, Link.

There is another River Ray west of Swindon that flows into the Thames east of Cricklade SU122939.
