Feildes Weir is a weir on the River Lea located in Hoddesdon, Hertfordshire at the confluence of the River Lea and River Stort. The weir marks the start of the Lower Lee. A channel of the man-made River Lee Flood Relief Channel is incorporated into the weir.
The weir has had a complex history of changes to channel control and bypassing over the years. Control was originally exercised by a barrage of gates and sluices.
In 1976, a 29 metres (95 ft) wide thin-plate weir was installed, with three vertical-lift sluices controlling a parallel flood relief channel. Flows average about 4.4 m3/s discharge over the weir; higher flows enter the flood channel. [1]
Angling in the weir pool is controlled by the Ware Angling Club and the River Lea Angling Club. [2] [3]
Hoddesdon is a town in the Broxbourne borough of the English county of Hertfordshire, situated in the Lea Valley. It grew up as a coaching stop on the route between Cambridge and London. It is located 3 miles (5 km) West of Harlow 4 miles (6 km) southeast of Hertford, 5 miles (8 km) north of Waltham Cross and 11 miles (18 km) southwest of Bishop's Stortford. At its height during the 18th century, more than 35 coaches a day passed through the town. It saw a boom in the mid 20th century as gravel was extracted from the area, but was exhausted by the 1970s. The lakes and water pits left behind have been used as leisure amenities. Today, Hoddesdon has a little light industry but is mainly a London commuter belt town. The town hosted the eighth Congrès International d'Architecture Moderne in 1951. It is twinned with the Belgian city of Dinant.
