Шаблон:Use Australian EnglishШаблон:Use dmy dates Шаблон:Infobox dam The Ewen Maddock Dam is an earth-fill embankment dam with an un-gated spillway across the Addlington Creek that is located in Landsborough in the South East region of Queensland, Australia. The main purpose of the dam is for potable water supply of the Sunshine Coast region.[1][2]

Location and features

The Ewen Maddock Dam is situated within the locality of Landsborough Шаблон:Convert from the town of Landsborough and approximately Шаблон:Convert southeast of Mooloolah and to supply the fast-growing region with town water. The dam is built across the Addlington Creek, a tributary of the Mooloolah River, and was commenced in 1973, completed in 1976, with a subsequent upgrade to the height of the spillway in 1982.[1]

The earthfill dam structure is Шаблон:Convert high and Шаблон:Convert in length to hold back Шаблон:Convert reservoir when at full capacity. From a catchment area of Шаблон:Convert, the dam creates an unnamed reservoir with an average depth of Шаблон:Convert. The surface area of the Шаблон:Convert long and Шаблон:Convert wide reservoir is Шаблон:Convert. The uncontrolled un-gated spillway has a discharge capacity of Шаблон:Convert.[3][1] The dam is managed by Seqwater.

Water supply

In the past, raw water from the dam has been supplied to a treatment plant at Caloundra.[4] Since 1988 Ewen Maddock Dam was not used as a water source due to a lack of working water treatment infrastructure.Шаблон:Citation needed In 2007, work began on an Шаблон:AUD30 million water treatment plant that will allow the dam to supply drinking water to the South East Queensland Water Grid, via the Northern Pipeline inter-connector.[5] The Queensland Government incorporated a Шаблон:Convert timber boardwalk along the reservoir's edge into the revised master plan when open space at Ewen Maddock Park was resumed for the treatment plant's construction.[6]

Recreation

Swimming is permitted in the reservoir. Boating is limited to paddle power, due to the likelihood that powered boats would agitate the water and cause noxious weeds to break apart and spread.[2]

Access is limited to daylight hours and no camping is permitted, except at a group camping site with cabins and dormitories, called the Ewen Maddock Dam Recreation Centre which is located at the south eastern end of the lake.[2][7]

Fauna and Flora

Ewen Maddock Dam is stocked with bass, silver perch, golden perch and southern saratoga, while bony bream is also present naturally.[2] As Of September 1, 2016 the lake is on the "Stocked impoundments" register and requires a "SIPS" permit for fishing. The lake is weedy and shallow, except in the northern parts close to the dam wall.[2] The weed species, Cabomba and Salvinia, have been the target of weed eradication programs by CalAqua.[8] The dam is a good place to see jabirus. South-eastern banks of the lake are heavily forested and protected within the Beerwah State Forest.
