River Lee Country Park
The River Lee Country Park is located in the Lee Valley Park and is managed by the Lee Valley Regional Park Authority. Covering on either side of the River Lee Navigation between Waltham Abbey and Broxbourne, it is an area of lakes, watercourses, open spaces and three Sites of Special Scientific Interest (SSSI) linked by footpaths and cycle tracks. The site straddles the Hertfordshire/Essex boundary. History Since the 1930s the area which was originally part of the River Lea flood plain has been the centre of the sand and gravel industry, as a result there are many mature gravel pits. Some of the lakes were used for land fill purposes. In a joint effort by the St Albans Sand and Gravel Co Ltd and the Lee Valley Regional Park Authority the area has been transformed, with much of the park a Site of Special Scientific Interest (SSSI) Olympics 2012 The park at the Showground site, Highbridge Street A121, Waltham Cross was the chosen venue for the 2012 Olympics canoeing eve ...

Fishers Green
Fishers Green is a settlement to the north of the town of Waltham Abbey, Essex, England, in the parish of Waltham Abbey. It lies on the flood plain of the River Lea. Description In the years following World War II much of the flood plain was given over to gravel extraction. The resulting lakes form part of the River Lee Country Park wetland reserve and the Turnford and Cheshunt Pits a SSSI. The lakes are popular for angling and sailing and are an important wildlife site. Seventy Acres Lake provides the ideal habitat for many species of birds and is the home of the national bittern watchpoint. Two watercourses flow through the locality; a natural channel of the River Lea known as the Old River Lea and the River Lee Flood Relief Channel. The Old River Lea is nationally renowned for its barbel and chub angling and is one of only four rivers in the UK where barbel are an indigenous species. In March 2012 an angler landed a chub from the River Lea, equalling the largest recorded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Lee Navigation2
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs, a ...

Otter
Otters are carnivorous mammals in the subfamily Lutrinae. The 13 extant otter species are all semiaquatic, aquatic, or marine, with diets based on fish and invertebrates. Lutrinae is a branch of the Mustelidae family, which also includes weasels, badgers, mink, and wolverines, among other animals. Etymology The word ''otter'' derives from the Old English word or . This, and cognate words in other Indo-European languages, ultimately stem from the Proto-Indo-European language root , which also gave rise to the English word "water". Terminology An otter's den is called a holt or couch. Male otters are called dogs or boars, females are called bitches or sows, and their offspring are called pups or cubs. The collective nouns for otters are bevy, family, lodge, romp (being descriptive of their often playful nature) or, when in water, raft. The feces of otters are typically identified by their distinctive aroma, the smell of which has been described as ranging from freshly ...

Great Bittern
The Eurasian bittern or great bittern (''Botaurus stellaris'') is a wading bird in the bittern subfamily (Botaurinae) of the heron family Ardeidae. There are two subspecies, the northern race (''B. s. stellaris'') breeding in parts of Europe and across the Palearctic, as well as on the northern coast of Africa, while the southern race (''B. s. capensis'') is Endemism, endemic to parts of southern Africa. It is a secretive bird, seldom seen in the open as it prefers to skulk in reed beds and thick vegetation near water bodies. Its presence is apparent in the spring, when the booming call of the male during the breeding season can be heard. It feeds on fish, small mammals, fledgling birds, amphibians, crustaceans and insects. The nest is usually built among reeds at the edge of bodies of water. The female incubates the clutch (eggs), clutch of eggs and feeds the young chicks, which leave the nest when about two weeks old. She continues to care for them until they are fully fledged ...

Wildfowl
The Anatidae are the biological family of water birds that includes ducks, geese, and swans. The family has a cosmopolitan distribution, occurring on all the world's continents except Antarctica. These birds are adapted for swimming, floating on the water surface, and in some cases diving in at least shallow water. The family contains around 174 species in 43 genera. (The magpie goose is no longer considered to be part of the Anatidae and is now placed in its own family, Anseranatidae.) They are generally herbivorous, and are monogamous breeders. A number of species undertake annual migrations. A few species have been domesticated for agriculture, and many others are hunted for food and recreation. Five species have become extinct since 1600, and many more are threatened with extinction. Description and ecology The ducks, geese, and swans are small- to large-sized birds with a broad and elongated general body plan. Diving species vary from this in being rounder. Extant spec ...

Carp
Carp are various species of oily freshwater fish from the family Cyprinidae, a very large group of fish native to Europe and Asia. While carp is consumed in many parts of the world, they are generally considered an invasive species in parts of Africa, Australia and most of the United States. Biology The cypriniformes (family Cyprinidae) are traditionally grouped with the Characiformes, Siluriformes, and Gymnotiformes to create the superorder Ostariophysi, since these groups share some common features. These features include being found predominantly in fresh water and possessing Weberian ossicles, an anatomical structure derived from the first five anterior-most vertebrae, and their corresponding ribs and neural crests. The third anterior-most pair of ribs is in contact with the extension of the labyrinth and the posterior with the swim bladder. The function is poorly understood, but this structure is presumed to take part in the transmission of vibrations from the swim bl ...

Cheshunt Lake
Cheshunt ( ) is a town in Hertfordshire, England, north of London on the River Lea and Lee Navigation. It contains a section of the Lee Valley Park, including much of the River Lee Country Park. To the north lies Broxbourne and Wormley, Waltham Abbey to the east, Waltham Cross and Enfield to the south, and Cuffley to the west. Historically an ancient parish in the Hertford hundred of Hertfordshire, it was granted urban district status in 1894. Waltham Cross, which became a separate ecclesiastical parish in 1885, historically formed the southern part of Cheshunt, and remained part of the Cheshunt Urban District until its abolition in 1974. The urban districts of Cheshunt and Hoddesdon merged in 1974 to form the Borough of Broxbourne, the area's current local authority district. Cheshunt was not re-established as a successor parish. At the 2011 census, Cheshunt had a population of 45,832. History and geography The Prime Meridian passes to the east of Cheshunt. The town name ...

SSSI
A Site of Special Scientific Interest (SSSI) in Great Britain or an Area of Special Scientific Interest (ASSI) in the Isle of Man and Northern Ireland is a conservation designation denoting a protected area in the United Kingdom and Isle of Man. SSSI/ASSIs are the basic building block of site-based nature conservation legislation and most other legal nature/geological conservation designations in the United Kingdom are based upon them, including national nature reserves, Ramsar sites, Special Protection Areas, and Special Areas of Conservation. The acronym "SSSI" is often pronounced "triple-S I". Selection and conservation Sites notified for their biological interest are known as Biological SSSIs (or ASSIs), and those notified for geological or physiographic interest are Geological SSSIs (or ASSIs). Sites may be divided into management units, with some areas including units that are noted for both biological and geological interest. Biological Biological SSSI/ASSIs may b ...

Small River Lea
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. Course The river leaves the Old River Lea below Kings Weir to flow through an aqueduct under the River Lee Navigation at Aqueduct Lock. It is joined by Turnford Brook at Turnford before meandering in a southerly direction past various lakes including the North Metropolitan and Cheshunt Lake and parallel with the West Anglia Main Line railway line. The river forms a boundary with the Lee Valley youth hostel at Cheshunt before flowing under Windmill Lane close to Cheshunt railway station. It flows close to the Lea Valley railway line and then between Bowyers Water and the River Lee Navigation before passing under the A121 road close to Waltham Cross to the west and Waltham Abbey to the east.

River Lee Flood Relief Channel
The Lee Flood Relief Channel (FRC) is located in the Lea Valley and flows between Ware, Hertfordshire, and Stratford, east London. Work started on the channel in 1947 following major flooding and it was fully operational by 1976. The channel incorporates existing watercourses, lakes, and new channels. Water from the channel feeds the Lee Valley Reservoir Chain. Design Flood defences are rated according to the probability that a particular level of flood water will be exceeded at least once in a specific period, so a 100-year flood represents a level that would only be expected to occur once in 100 years. This is often known as 1 per cent protection. The level of flooding in 1947 was estimated to be a 1.4 per cent occurrence, and the flood channel, when it was first designed, was built to cope with this level of flooding. Since it was completed in 1976, there have been no major flood events in the Lea Valley, although there have been three occasions when the river system was f ...

River Lea
The River Lea ( ) is in South East England. It originates in Bedfordshire, in the Chiltern Hills, and flows southeast through Hertfordshire, along the Essex border and into Greater London, to meet the River Thames at Bow Creek. It is one of the largest rivers in London and the easternmost major tributary of the Thames. The river's significance as a major east–west barrier and boundary has tended to obscure its importance as north–south trade route. Below Hertford the river has since medieval times had alterations made to make it more navigable for boats between the Thames and eastern Hertfordshire and Essex, known as the Lee Navigation. This stimulated much industry along its banks. The navigable River Stort, the main tributary, joins it at Hoddesdon. 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. An artificial waterway known as the New River, opened in 1613, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
