The River Leach is a river tributary to the River Thames, in England which runs mostly in Gloucestershire. It is approximately 18 miles (29 km) long, springing from the limestone uplands of the Cotswolds. In parts of its course it becomes a seasonal bourn, only running above ground when there is sufficient rainfall. Despite its small size it gives its name to two towns and a pair of villages.
The clapper bridge crossing the River Leach is named “Keble’s Bridge” after the early 19th century the churchman John Keble who was curate to the church of St. Michael & St. Martin in the village. John Keble was a founding member of the Oxford Movement.
