The King George VI Reservoir sits between Stanwell Moor and Staines upon Thames, south-west of Heathrow, England. It is between Staines Moor and a north–south road abutting the Staines Reservoirs. The reservoir was opened in November 1947 and named after the then reigning monarch George VI. It is owned by Thames Water.
