Multi-use track closed at Moololah Connection Road (Tuesday, 9 April 2013)

The main multi-use track is closed at the causeway on the Mooloolah Connection Rd side of the dam.
 
The causeway is underwater and erosion has made it unsafe for users. The area is cordoned off and will remain closed until the water level recedes and repair work is completed. The remainder of the track remains open.

Ewen Maddock Dam – Stage 1 Safety Upgrade complete

Stage 1 of the safety upgrade works at Ewen Maddock Dam are now complete.
 
The works were undertaken in order to meet dam safety requirements identified during a Dam Safety Review in 2010, and to comply with Queensland Guidelines on Acceptable Flood Capacity (AFC).
 
Stage 1 works involved strengthening and widening the dam wall embankment, as well as installing relief wells to control groundwater levels.
 
Stage 2 Works are planned for the future to improve the spillway capacity and raise the dam wall.
