Although the Midford Brook is named on Ordnance Survey maps,[3] the Environment Agency does not recognise it, instead identifying the Wellow Brook as continuing to the Avon.[4]
The Midford Brook has a catchment area of 147.4 km2 which is largely over impermeable Lias. The deep steep-sided valley means that it responds rapidly to rainfall.[5]
