The River Ingrebourne is a 43km tributary of the River Thames which rises near Brentwood as the Weald Brook. It passes underneath the M25 and flows past the urban areas of Harold Park and Harold Wood where it is joined by Carter's Brook.
Running between Hornchurch and Upminster into the Ingrebourne Valley it feeds nationally important reed beds and marshland as it passes. From Rainham it passes through industrial areas, flowing into the Thames as Rainham Creek through a tidal sluice at Frog Island.
