River Murray and Lower Lakes catchment risk assessment for water quality: Results and management options 7 Goolwa to Wellington and Coorong District LAP areas assessment 7.1 Description of the area This chapter combines the two Local Action Planning (LAP) areas: Goolwa to Wellington (GW) and the Coorong District (CD). The key water resources within this region are the large (85,000 ha) and shallow (2–3 m deep) freshwater Lakes Alexandrina and Albert, and the saline Coorong (140 km long, 2–3 km wide)( Figure 7.1). The River Murray enters Lake Alexandrina near Wellington and Lake Albert is connected to Lake Alexandrina by a narrow passage near Narrung. The Lower Lakes and Coorong are highly ecologically significant (see eg Phillips et al. 2005) and have been identified as one of six significant ecological assets across the entire Murray–Darling Basin. The region was selected because of its unique ecological qualities and hydrological significance and social, cultural and economic values for local and state communities including the Ngarrindjeri, the traditional owners of the region, for whom the lands and waters (or Ruwe), are a living body (MDBC 2005). Goolwa to Wellington LAP The GW LAP area, in the southernmost section of the Murray–Darling Basin, covers an area of about 265,000 ha 11 and includes the townships Goolwa, Clayton and Milang (Alexandrina Council jurisdiction). The Goolwa population of about 2400 swells during holiday periods and residential development is currently increasing in the area. The LAP area includes a large area of Lake Alexandrina and encompasses all the plains and catchments that drain into the lake, from Goolwa to Wellington. This includes Currency Creek, Tookayerta, Finniss, Angus and Bremer-Barker catchments, and adjoining plains. Hindmarsh and Mundoo Islands at the mouth of the River Murray are also included. The main agricultural land use on the plains is cropping but there are also dairy farms, vineyards and vegetable production. Grazing is the main land use on Hindmarsh and Mundoo islands. Water management in the catchment area has undergone a number of significant changes in the last 150 years with diversion of surface drainage, construction of dams, groundwater extraction and establishment of an irrigation industry (CSIRO 2004). Land and water salinisation is currently a major problem, and salt and stream salinity levels are predicted to rise in the future (Dooley & Henschke 1999). Salinisation, wetland and watercourse degradation, lakeshore erosion, overuse of water resources and irrigation management are key issues being targeted by the GW LAP group 12 and other agencies. Coorong District LAP The CD LAP area extends from just above Tailem Bend and Peake in the north, to just above Keith in the Upper South East (USE). Coorong National Park, Lake Albert and Lake Alexandrina form its western boundary (Figure 7.1). The land area covers 883,500 ha, the lakes 46,800 ha 13 . Townships include Meningie and Raukkan (Coorong District Council jurisdiction). Land use in this LAP area is predominantly a mixture of cropping and grazing with 0.6% of the area irrigated for dairies, fodder and lucerne seed (CD LAP 2000). Significant areas of wetlands and national parks lie within the CD LAP area, as does the mouth of the River Murray. 11,13 This report only considers the portion of the LAP area that is part of the water protection areas defined under the Environment Protection Act 1993 and River Murray Act 2003. 12 See website for more information 191
