Introduction A range of previous studies have looked at land along the flood plain of the River Murray. The most detailed was by Hollingsworth, I D (1989) who undertook a reconnaissance soil survey of the Chowilla Anabranch System of the River Murray. Several previous reports have generally described the flood plain areas relevant to this…
DetailsThe KatFish Reach project area which includes the Katarapko and Eckert Creeks Anabranch system has been impacted by the construction of numerous barriers over the last 80 years. These barriers have been constructed for a number of reasons starting with the construction of Lock 4 on the main River channel and associated structures of the…
DetailsConservation Asset Condition Summary Katarapko Creek (Segment 1) (13.7Km) A diverse section of healthy waterway, with a channel width ranging from 40 to 80 meters. In stream vegetation is dominated by Floating Pondweed with patches of Common Reed, Cumbungi, Water Primrose, Ribbon Weed, Curly Pondweed and Three-cornered Bulrush with high numbers of snags throughout the…
DetailsIntroduction The Katarapko-Eckert Creek demonstration reach in the Riverland of South Australia lies just to the south-west of the prominent fruit and wine growing town of Berri, and north and opposite the town of Loxton on the River Murray. The demonstration reach is a floodplain habitat of the River Murray that includes The Splash, Sawmill…
DetailsIntroduction The Department of Environment and Heritage (DEH) have engaged Australian Water Environments (AWE) to undertake a preliminary desk top salinity impact assessment of the hydrological management options that are proposed for Katfish Reach. The study area is located south to south-west of the township of Berri on the River Murray (Figure 1.1). The Katfish…
DetailsINTRODUCTION Department for Environment and Heritage (DEH) commissioned Water Technology to develop a hydraulic model for the Eckert Island section of Katfish Reach to assist decision makers in the development of a number of waterway management options. This report reviews previous studies and all available data , outlines the proposed hydraulic modelling framework, and scopes…
DetailsExecutive Summary River regulation in the Murray-Darling Basin has altered the natural hydrological regime of the Murray River and led to decreases in abundance and distribution of native fish populations. The Katarapko Anabranch system provides hydraulic and habitat diversity (e.g. slow and fast flowing creeks and backwaters) in a region of the lower Murray River…
DetailsINTRODUCTION Department for Environment and Heritage (DEH) commissioned Water Technology to develop a hydraulic model for the Eckert Island section of Katfish Reach to assist decision makers in the development of a number of waterway management options. A coupled one and two-dimensional hydraulic MIKE FLOOD model of the Katfish Reach floodplain, including the Murray River…

DetailsEcological Monitoring Five Sites along The Splash within the Katarapko Floodplain were selected. Sites were selected on available habitat and accessibility. At each of the five sites water quality, fish, vegetation, waterbirds and frogs were monitored. Separate sites were established for both tree condition and groundwater transects. Water quality was monitored on a monthly basis,…
DetailsExecutive summary The ‘Katfish Reach’ initiative was developed in 2007 to provide a holistic approach and to facilitate community involvement in the management of the health of the Katarapko Anabranch system and its associated floodplain (from hereon in referred to as ‘Katfish Reach’; Katfish Reach Steering Group, 2008a). The vision of the ‘Katfish Reach’ initiative…
DetailsIntroduction Katfish Reach Project Description The Katfish Reach Project is located on the Katarapko/Eckert Creek anabranch system between Berri and Loxton along the River Murray in South Australia (Figure 1.1). The area hosts the River Murray National Park, Katarapko, Gerard Aboriginal Reserve as well as crown and private land. The total area is nearly 9,000…
DetailsIntroduction 1.1 Site Description Katfish Reach is a demonstration reach for native fish situated within the Katarapko-Eckert Creek anabranch system between Berri and Loxton on the River Murray in South Australia (Figure 1) (Katfish Reach Steering Group, 2008). Katfish Reach isabout 9,000 hectareswith the total anabranch length approximately 38km. The River Murray forms the eastern…
DetailsBackground The purpose of the demonstration reach is to show, by example, how river and floodplain rehabilitation can be achieved by well-integrated management intervention such as riparian zone rehabilitation, alien/pest species management, re-snagging, improvements to water quality, providing environmental flows, improved fish passage and enhanced aquatic vegetation. The successful rehabilitation of a reach or floodplain…
