Lake Monger

From Wikipedia, the free encyclopedia

This article is about Lake Monger in suburban Perth. It should not be confused with Mongers Lake in east Perenjori in the Mid West region of Western Australia which is part of the major inland drainage system in that region and is 184 km long and 7.5 km wide.

Lake Monger is a large urban wetland on the Swan Coastal Plain in suburban Perth, Western Australia nestled between the suburbs of Leederville, Wembley and Glendalough (31.9294° S 115.8265° E). Less than five kilometres from the city of Perth and situated alongside the Mitchell Freeway, it runs approximately north-west to south-east towards the Swan River and consists of 70 hectares of mainly open shallow water with an island of 1.3 hectares in the south-west corner. The 110 hectares of lake and the surrounding parklands are known as the Lake Monger Reserve.

The lake is presently used extensively for recreation as well as being a major tourist attraction with up to 12,000 visitors per week (Middle, 1988). Activities include bird watching and exercise.

A 3.5km paved walking/cycling track encircles the lake which takes about 30 minutes to traverse by foot. Ample carparking, playground equipment and barbecue facilities are also provided.

[edit] Name

The indigenous Australian Noongar people of the area called it Lake Galup, Lake Kalup or Keiermulu.

After European settlement, it became known as either Large Lake or Triangle Lake (based on its roughly triangular shape) before being named Monger's Lake in 1831. In April 1932 it was changed to its current name of Lake Monger.

[edit] Pre-European history

Little is known precisely about the use of the lake by the Noongars prior to the British settlement other than the area was known to be within the area inhabited by those people. Given its geographical features, it would undoubtedly have been used regularly as a significant camping and hunting site with black swans and other wildfowl as well as turtles, frogs, gilgies and mudfish hunted as food.

Associated with the lake is the Wagyl, part of Noongar mythology. The myth describes the track of a serpent being, who in his journey towards the sea, deviates from his route and emerges from the ground which gives rise to Lake Monger.

[edit] History since 1832

[edit] Perth wetlands

The lake was originally part of a series of freshwater wetlands running north from the Swan River along the coastal plain for approximately 50 km. Lake Monger was grouped with the Georgiana Lake and Lake Sutherland (both near Mitchell Freeway, near Sutherland and Newcastle streets) and Herdsman Lake and together the area made up what was known as "The Great Lakes District".

European settlement led to many of the wetlands areas being drained for land reclamation to take advantage of the fertile soil for farming enterprises, and for expansion of parks and recreation areas. Lake Monger and Herdsman Lake are the last two major wetlands remaining within close proximity to the city. The City of Perth itself sits on an area of reclaimed wetlands. It is thought that between 49% (Riggert, 1966) and 80% (Godfrey, 1989) of the wetlands on the coastal plain have been drained, filled or cleared since 1832.

Other lakes and swamps in the immediate northern vicinity of the early Perth township were Lake Kingsford (site of the current Perth railway station), Lake Irwin (Perth Entertainment Centre) and further north were Stone's Lake (Perth Oval), Lake Poullet (First Swamp, part of what is now Birdwood Square), Lake Thomson (Mews Swamp, between Lake, Brisbane and Beaufort streets) and Lake Henderson (parts of what is now Robertson Park and Dorrien Gardens). Further north still lay Second Swamp (Bulwer Street, east of Lake Street), Third Swamp (Hyde Park) and Three Island Lake and Smith's Lake (now Charles Veryard Reserve). Many of these lakes formed a natural interconnected drainage system which found its way into the Swan River at East Perth through Claise Brook.

In 1833, water draining from Lakes Kingsford, Irwin, Sutherland and Henderson was used to drive a water-driven mill located in Mill Street.

[edit] Timeline

• In 1829, a British expedition established the Swan River Colony and in 1830, Lake Monger was the site of a minor skirmish between white settlers and a Noongar by the name of Midgegooroo (Miller, 1980).

• By 1832, the lands around the lake had been subdivided into eight lots: a southern one was acquired by John Henry Monger and described as 200 acres [81 hectares] of Perthshire Location Ae abutting Lake Monger. William H. Leeder took up adjoining land grants at Perthshire Locations Ac and Ad, to which he later added Locations 1, Ax and Ay. This area is now known as the suburb of Leederville (Bekle, 1981).

• From 1850 to 1868, the arrival of convicts swelled the population and market gardening on the northern side of the city expanded to meet the greater demand for food. By the 1870s, "Perth was surrounded by gardens in a fan which spread from Cole’s garden in the east to Leeder’s in the west" (Stannage, 1979).

• In 1902, the Leederville Council appointed a board under the Parks and Reserves Act 1896 to manage the Lake (Metcalfe, 1988).

• In 1909, construction of a drain was completed which connected the lake with the Swan River and which allowed the water level to be managed (Bekle, 1981; Metcalfe, 1988). This drain still operates today.

• In 1912, the lake had an area of 111 hectares (Miller, 1980).

• In the 1920s, the lake and surrounding areas, mainly to the west and south were still being used as a campsite by Noongars and providing food (Metcalfe, 1988).

• From the early 1920s, the newly formed City of Perth started acquiring land which was until then being used as Chinese market gardens and dairies for conversion into public parks and recreation areas. This included land mainly around the eastern side of the lake. By 1928 the gardeners were gone and by 1930, 50 hectares of land had been bought by the Council to be developed as part of the Lake Monger Reserve (City of Perth).

• After many years of delays due to lack of funds, silt dredging works commenced in May 1932 to reclaim 20 hectares of the mainly swampland (City of Perth).

• By June 1933, 110,000 tons of silt had been pumped, allowing 4.8 hectares of land to be reclaimed. Much of the fringing vegetation was removed and replaced with lawns. The southern shore of the lake was developed with a kiosk, bathing sheds, boat house and a T-shaped jetty. A swim-through on the lake was held as part of the celebrations, as well as a canoe race involving Leederville, Wembley and Mount Hawthorn Boy Scouts and a series of bonfires. The lake was used extensively for picnicing, yachting, swimming and fishing. Some areas of the lake were further dredged to improve yachting (Miller, 1976; Metcalfe, 1988, City Planning Department, 1969).

• As well as the dredging silt, reclamation was assisted by the dumping of rubbish and raw sewage from nightsoil collectors on the north-eastern side. By 1936 the water quality had deteriorated badly and reports of nuisance chironomids (midges) were being made (Perth City Council, 1960).

• In 1939 a youth drowned in the lake, which led to boating being forbidden and swimming discouraged.

• Between 1950 and 1964, a 1.8 m deep sanitary landfill in the north and north-eastern parts of the lake reclaimed further wetlands. This was covered by 60 cm of clean soil (Slattery, 1963).

• In the late 1950s, a comprehensive plan for the lake was drawn up as part of Gordon Stephenson's 1955 “Plan for the Metropolitan Region, Perth and Fremantle and which saw the provision of land within the reserve set aside for the Mitchell Freeway, which was built in the 1970s.

• In the 1960s a small island was created in the south-western corner to act as a bird refuge.

[edit] Flora and Fauna

A reed island was constructed in the 1960s to provide a summer refuge for birds. 38 species of birds have been sighted including black swans, shags and pelicans.

The lake also supports long-necked tortoises, large skinks, and two species of frogs. Fish common to the lake are all introduced species including goldfish, carp, mosquito fish and English perch.

Vegetation in the 1800s comprised rushes, swamp paperbark, blackboy, wattle and tea tree, but with land reclamation, rushes were removed to plant lawns and construct sandy beaches. None of the banksia and few paperbarks remain and trees are now generally confined to a narrow strip surrounding the shoreline, mainly on the northern and eastern sides.
