Weir pool raising along River Murray

3 September 2015

The Department of Environment, Water and Natural Resources (DEWNR) is intending to raise the water level in the weir pools at locks 2 and 5 of the River Murray.

This event is to mimic the natural variability of water levels that occurred before the weirs and locks were built. The intent is to raise the water level in both weir pools to 50 centimetres above the normal pool level during spring.

The water will be raised until late spring/early summer and DEWNR urges water users to use caution when using boat ramps, and navigating near river banks and bridges (including the Paringa Bridge), due to the changed conditions. We also ask that water users slow down near shack communities, jetties and the water's edge to minimise the possibility of bank erosion and damage caused by wave wake effects.

The goal of the project is to mimic a spring pulse to create additional habitat for native species in the River Murray, improve the health of the vegetation near the channel and connected floodplains and wetlands, and increase the numbers of frogs, birds and fish in the system.

If you want to know more, including information about modelling showing where the water is expected to go, can be found on the DEWNR website.
