 A minor spring in The Mill Field in Mill Hill is probably a source of a tributary of Burnt Oak Brook, but the brook itself is first visible in Simmonds Mead Open Space, a small green open space at the junction of Watford Way and Lawrence Street.The stream then again passes through an underground pipe to re-emerge in the north-west corner of Lyndhurst Park.It goes along The Meads and under Deansbrook Road to pass through Abbots Road Allotments into Watling Park.
