Bayford Brook is a minor tributary of the River Lea.^[1] It forms in the hills near Bayford, Hertfordshire and joins the River Lea at Horns Mill Weir.

The brook is mostly dry during periods of little rain, as it has a steady gradient with few pools to collect water.

The brook is most easily viewed towards its northernmost point where is runs between the two parallel Brickendon Lanes before disappearing into a culvert (illustrated in the photograph). It can also be clearly seen to the left of Brickendon Lane heading away from Hertford at coordinates 51.781884,-0.081008
