This map shows the appoximate outline of the catchment area which feeds into the measuring station at Banbury. All the rain which falls onto the blue area, that is not absorbed into the soil or evaporated, will eventually flow to the sea via Banbury.
This local monitoring station catchment area is contained within the Cherwell and Ray management catchment area.
