[PAR] [TLE] Woollens Brook [SEP] 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 ( ). [PAR] [TLE] River Lea [SEP] 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.
