This map shows the appoximate outline of the catchment area which feeds into the measuring station at Oulton Lemonroyd. 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 Oulton Lemonroyd.
This local monitoring station catchment area is contained within the Aire and Calder management catchment area.
