The demonstration reach is a floodplain habitat of the River Murray that includes The Splash, Sawmill…


Katfish Reach Hydrological Options – Salinity Impact Assessment

Introduction 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…


Katfish Reach Modelling Calibration and Scenarios

INTRODUCTION 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…


Gerard Trainee Baseline Survey of The Splash (Katarapko) and Gerard Swamps

Ecological 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,…

Eckert Creek Wide Water Ecological Monitoring Report 2009

Background 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…
