Context: Rags Brook is a tributary of the Small River Lea, which is a tributary of the River Lea.  Rags Brook rises in the hills between Goffs Oak Cuffley in Hertfordshire, England.  Brookfield Lane follows the course of the brook and the Brookfield Centre reflects the brook in its name. Bayford Brook is a minor tributary of the River Lea.  It forms in the hills near Bayford, Hertfordshire and joins the River Lea at Horns Mill Weir. Knapps Brook is a minor tributary of the River Lea in Bedfordshire, England.  The source of the river Lea is on Leagrave Common in Luton.  It forms from a combination of brooks from East End, Houghton Regis and from the Lewsey Estate near the old Lewsey Farm.  It joins the River Lea from culverts under the railway embankment and Toddington Road in Leagrave. Turnford Brook is a minor tributary of the River Lea.  The brook flows through the Borough of Broxbourne for approximately 3 mi . Woollens Brook, a minor tributary of the River Lea, rises close to Ermine Street, south of Hertford Heath ( ) and flows through Box Wood in Hertfordshire.  The stream flows under both the A10 and the Dinant Link Road roundabout with Amwell Street.  The stream then runs parallel with Essex Road before going under it and through the Lampits where it joins another minor tributary of the River Lea, the River Lynch, at Bridgeways ( ). The River Lynch, also known as the Lynch Brook, is a minor tributary of the River Lea in Hoddesdon, Hertfordshire, England. Pymmes Brook is located in North London and named after William Pymme, a local land owner.  It is a minor tributary of the River Lea.  The brook mostly flows through urban areas and is particularly prone to flooding in its lower reaches.  To alleviate the problem the brook has been culverted in many areas.  Part of it is a Site of Borough Importance for Nature Conservation, Grade II. The River Lea in England originates in Marsh Farm, Leagrave, Luton in the Chiltern Hills and flows generally southeast, east, and then south through east London where it meets the River Thames, the last section being known as Bow Creek.  It is one of the largest rivers in London and the easternmost major tributary of the Thames.  Its valley creates a long chain of marshy ground along its lower length, much of which has been used for gravel and mineral extraction, reservoirs and industry.  Much of the river has been canalised to provide a navigable route for boats into eastern Hertfordshire, known as the Lee Navigation.  While the lower Lea remains somewhat polluted, its upper stretch and tributaries, classified as chalk streams, are a major source of drinking water for London.  A diversion known as the New River, opened in 1613, abstracts clean water away from the lower stretch of the river for drinking.  Its origins in the Chilterns contribute to the extreme hardness (high mineral content) of London tap water. The Small River Lea is a minor tributary of the River Lea, which flows through the Lee Valley Park between Cheshunt and Enfield Lock.  It forms part of the Turnford and Cheshunt Pits Site of Special Scientific Interest (SSSI) as it flows through the River Lee Country Park. Spital Brook is a minor tributary of the River Lea which rises in Hoddesdonpark Wood in the county of Hertfordshire, England.  Spital Brook flows eastwards from Hoddesdonpark Wood, passing through Barclay Park, the former Hoddesdon Common, on its journey to the Lea, while an unnamed parallel stream to the south has been diverted to form ornamental waterbodies located within the former parkland of Broxbournebury.  The stream crosses the Roman road, Ermine Street, before going under the A10 and Cock Lane.  The original crossing place or ford of Spital Brook in Cock Lane remains and the original route it took ran parallel to the brook in a north-south direction.  The brook passes through its namesake area, Spital Brook and marks the traditional boundary between the two parishes of Hoddesdon and Broxbourne.  The stream runs parallel to the Lea Valley Lines by Broxbourne Station until it meets the River Lea close to Broxbourne Riverside, the former Broxbourne Lido.
