Breakout Creek wetlands 1999 to 2010 The development of innovative projects The Adelaide and Mount Lofty Ranges Natural Resources to restore damaged watercourses, prevent Management Board (then the Torrens Catchment Water Management Board) and the City of West Torrens developed pollution and provide habitat to native flora a concept plan in consultation with the local community and fauna is a major priority for the Adelaide to achieve these improvements. and Mount Lofty Ranges Natural Resources The concept plan was delivered in two stages and completed Management Board. in 2010. The aim was to create a viable ecosystem that offered recreational facilities that could be enjoyed by the local community, while delivering water quality improvements and Breakout Creek, located at the coastal end of the River Torrens, maintaining flood protection. has been the focal point of a long-term watercourse rehabilitation project for over 10 years. Stage one, completed in 1999, centred on the 500-metre stretch of the river upstream of Henley Beach Road. Stage two focused The rehabilitation involved widening and deepening the existing on the 700-metre stretch downstream of Henley Beach Road, waterway, constructing viewing platforms and public access paths, to Tapleys Hill Road, and was completed in 2010. removal of weeds and extensive planting of native vegetation.

Opinions were canvassed from a range of stakeholders and partners over more than a decade. Prior to the commencement of detailed planning for Stage 2 of the project, a Social Impact Assessment was conducted. This ensured that the issues and ideas of the community were identified, explored and documented, particularly the impact on horse agistment in the area. Feedback garnered from the community mostly centred on themes such as recreation, walkways and viewing platforms, and a bridle path linking the Lockleys Riding Club with the horse agistment areas between Tapleys Hill Rd and the sea. Where possible, the feedback and ideas were incorporated in the final plan. The Torrens and the Reedbeds At the time of European settlement, coastal sand dunes formed a barrier that prevented water from the River Torrens flowing out to sea. During rainy seasons, floodwaters filled a series of linked wetlands from Grange to Glenelg. This area of wetlands was known as the Reedbeds. Breakout Creek was originally a small channel dug by a Fulham landholder to divert water south towards the Patawalonga River during floods. During the 1930s, a deeper, wider, straighter channel was dug through the sand dunes to the sea to alleviate seasonal Note: Suburbs, roads, railways and topography as existed in July, 1882. flooding issues.

Linear park The River Torrens boasts Australia’s earliest and largest hills- to-coast linear park along 30 kms of its length. The park offers bicycle and walking tracks as well as playgrounds and other recreational facilities dotted throughout.
