Flow requirements and resource delivery to the Lower Murray Lakes and Northern Coorong

As discussed in the previous milestone reports, the drawdown of water levels in the Lower Lakes to unprecedented levels has provided an additional focus for the project. This has been done to provide relevant information to the managers and assist with both the short-term and long-term management of the region. It has included investigating the changes water quality during drawdown and likely changes in water quality upon reflooding the lakes.

Water allocation to River Murray wetlands: a basin-wide modeling approach

The primary aim of this project was to relate the water regime preferences of wetland plants to hydrology throughout the Murray River Basin and to predict the volume of additional water required to achieve optimal plant species diversity. This report details the methods and key findings of the project which examined the impact of regulation and changes in water allocation on the community composition of wetland plants through the Murray River basin. Due to a lack of primary data, it deals (more)...

Mallee Fire and Biodiversity Project

Determining appropriate fire regimes in the Murray Mallee

Project Aim:

To identify the properties of habitat mosaics produced by fire that enhance the persistence and status of a broad range of taxonomic groups (birds, mammals, reptiles, key invertebrates and plants) in eucalypt-dominated mallee habitats.

Managing Weeds Under Future Scenarios for Environmental Flows in the Murray River

Appendix

This project examined relationships between hydrological parameters relating to flooding and the location and abundance of exotic plant species in River Murray floodplain systems.

Making the most of scant environmental flows

Maintaining the iconic river red gum and black box woodlands of the Lower Murray Valley

Presents findings from a Land & Water Australia PhD study undertaken on the Lower Murray Valley floodplain in South Australia. Primary study sites covered the region from Morgan in the west to Chowilla on the NSW border.

Investigating lake/groundwater interactions at Lake Tutchewop

Salinity is an on-going environmental concern that causes damage to agricultural land, downstream water users, aquatic ecosystems and biodiversity, as well as to regional and urban infrastructure. One strategy to manage increasing salinity in the Murray Darling Basin is the construction of 13 major salt interception schemes that divert 550,000 tonnes of salt away from the Murray River each year (Figure 1). The Barr Creek Drainage Disposal Scheme is one of these schemes diverting saline water into (more)...

Ecological risk assessment case study for the Murray Irrigation region - Report 2

This report - Ecological Risk Assessment Case Study for the Murray Irrigation Region - is the second in a series of five produced by NPSI project UMO45 Delivering Sustainability through Risk Management. An ecological risk assessment (ERA) was undertaken in the Murray irrigation region in southern NSW to assess the risks to the ecological values (or assets) from irrigation and other (more)...

Root Zone Salinity Risks in the Lower Murray Districts

As a result of improved irrigation management and systems, growers in the Lower Murray (Riverland-Sunraysia) horticultural region have improved their water use efficiency (WUE) over the past two decades from about 50% to about 80%. However a negative consequence of this achievement is the emerging risk of salinity build-up in the root zone, threatening the sustainability of the region (Biswas et al. 2005a; Biswas et al. 2005b). The amount of irrigation applied must account for (more)...
