Sunwater has begun work at Fred Haigh Dam to repair scour damage from previous floods and restore the functionality of the downstream spillway channel. The initial stage of works will continue until late December 2019, weather permitting.
The scouring which resulted from the energy impact of flood water on the natural spillway channel and has been subject to regular monitoring.
While there is no immediate dam safety risk, Sunwater has now deemed that works are necessary in working towards reinstating the area downstream of the spillway to its pre-flood condition.
Initial works in 2019 includes:
- installing anchors within the natural spillway channel adjacent to the spillway chute
- filling scour holes with reinforced concrete to reduce possibility of further scour
- grading filled scour areas within the spillway channel to match the natural slope of channel
- earthworks to clear debris in the river channel and reduce water pooling next to the dam embankment wall.
The project will not impact public access to recreational facilities such as boat ramps or picnic areas. For more information visit https://bit.ly/2roPqdc
