Pondage Remediation - Burrier Pumping Station - Burrier and Illaroo

The pondage, comprising a natural shingle bar and man-made rock weir, was damaged by the 2019/2020 catchment-wide bushfires and subsequent flood events which caused breaches in both the shingle bar and weir. The breach in the shingle bar has created and established a low-flow “northern channel” with which water bypasses the pondage located within the “southern channel” . Breaches in the weir have reduced the capacity of the pondage. As the pondage becomes too low to pump from during low flow periods (160ML/day), these breaches have, and will continue to, significantly impact Shoalhaven’s water supply.
The proposed activity is the remediation of the pondage which would include installation of a training wall at the shingle bar breach using rock bags and salvaged logs, and remediation of the weir by reinstating rock material.
Works would also involve the implementation of safeguards and mitigation measures prescribed in Section 7 of the REF.
