Terrigal Lagoon, an intermittently closed intermediate saline coastal lagoon, is located on the Central Coast region of New South Wales, Australia. Terrigal Lagoon is located between the towns of Terrigal and Wamberal, and adjacent to the east coast, about 85 kilometres (53 mi) north of Sydney.
|Location||Central Coast, New South Wales, Australia|
|Type||Intermittently closed intermediate saline coastal lagoon|
|Primary outflows||Tasman Sea of the South Pacific Ocean|
|Catchment area||8.9 square kilometres (3.4 sq mi)|
|Surface area||30 hectares (74 acres)|
|Average depth||0.5 metres (1 ft 8 in)|
|Water volume||151.2 megalitres (5.34×106 cu ft)|
|Surface elevation||0 m (0 ft)|
The lagoon has a surface area of approximately 30 hectares (74 acres) and a catchment area of 8.9 square kilometres (3.4 sq mi). When full, the Terrigal Lagoon covers an area of around 29 hectares (72 acres).
A large part of the upper catchment area of Terrigal Lagoon is rural land, most of which has been cleared. The lower slopes in the vicinity of the lagoon contain extensive urban development. South and west of the lagoon is the township of Terrigal. The northern part of the catchment includes part of the suburb of Wamberal. A large knoll of land rises from the centre of the catchment separating the two arms of the lagoon. The Terrigal Country Club and Golf Course are located at the limit of the North Arm. The North Arm of the creek drains an area of approximately 4.5 square kilometres (1.7 sq mi) and the West Arm 3.7 square kilometres (1.4 sq mi).
From 2005 to 2008 a study, led by Dr. John Marsdale from the University of Newcastle, completed a region-wide survey of waterways. As part of the study, the investigation included the availability of sunlight for plants, turbidity levels, population density of plants and animals residing in the lagoon area, potassium levels, oxygen levels, and water pH levels.
The research team found that abiotic features in the area greatly affected biotic organisms within the lagoon. Marsdale's team also found that the light level available to shrubbery in the lagoon lessened over during the course of the study due to growth of taller trees taking critical sunlight from the smaller grounded plants. Marsdale discovered disturbingly high potassium levels in the area in comparison to elsewhere in the region. The potassium levels were effecting not only the fish in the lagoon but also the multitudes of plants that lined the waters edge. The team also found that there was an overall decrease in the distribution of species in the lagoon area particularly concerning animals and some fish species.
The Avoca Lake, formerly known as Avoca Lagoon and as Bulbararing Lagoon, is an intermittently closed intermediate saline coastal lagoon that is located on the Central Coast region of New South Wales, Australia. Avoca Lake is located between the beachside settlements of North Avoca and Avoca Beach, and adjacent to the east coast, about 85 kilometres (53 mi) north of Sydney.List of lakes of Australia
Natural freshwater lakes in Australia are rare due to the general absence of glacial and tectonic activity in Australia.Rivers of New South Wales
This page discusses the rivers and hydrography of the state of New South Wales, Australia.
The principal topographic feature of New South Wales is the series of low highlands and plateaus called the Great Dividing Range, which extend from north to south roughly parallel to the coast of the Coral and Tasman seas of the South Pacific Ocean.
The two main categories of rivers in New South Wales, are those that rise in the Great Dividing Range and flow eastwards to the sea, the Coastal NSW Rivers; and those that rise on the other side of the crest of the range and flow westward, the Inland NSW Rivers. Most of the inland rivers eventually combine into the Murray-Darling network of rivers, which drains to the sea in South Australia.Wakool River
Wakool River, an anabranch of the Edward River that is part of the Murray River catchment within the Murray-Darling basin, is located in the western Riverina region of south western New South Wales, Australia.
The Wakool River splits from the Edward River (itself an anabranch of the Murray) near Deniliquin, and flows generally to the west, southwest, northwest, and then west, joined by eleven minor tributaries, including the Niemur River. The Wakool is rejoined by the Edward River near Kyalite, not far from where it runs back into the main channel of the Murray, at Wakool Junction; dropping 43 metres (141 ft) over the course of its 363 kilometres (226 mi) length.Wamberal, New South Wales
Wamberal () is a coastal suburb of the Central Coast region of New South Wales, Australia, just north of Terrigal. It is part of the Central Coast Council local government area and is located adjacent to the Wamberal Lagoon.Wamberal Lagoon
Wamberal Lagoon, an intermittently closed intermediate saline coastal lagoon, is located on the Central Coast region of New South Wales, Australia. Wamberal Lagoon is located between the beachside settlements of Forresters Beach and Wamberal, and adjacent to the east coast, about 87 kilometres (54 mi) north of Sydney.Wolgan River
The Wolgan River, a watercourse of the Hawkesbury-Nepean catchment, is located in the Central Tablelands region of New South Wales, Australia.
