Water levels inside Isabella Pond have been lowered in preparation for planned rectification works to be undertaken on the Isabella Weir walls.
Works are expected to get underway this week at which time Isabella Pond will be completely drained. The water levels in the downstream Tuggeranong Pond will also be reduced by approximately one metre to enable access to the downstream face of Isabella Weir.
Isabella Weir is being upgraded to bring it into line with national best practice guidelines and the recently introduced ACT Dam Safety Code. The upgrade has included the widening of the Weir to increase its capacity to accommodate major floods.
Major works as part of the upgrade were completed in late 2018 and the Weir was allowed to fill to identify any minor defects.
Rectification works will take approximately one month to complete. Following these works, the Weir and Pond will be allowed to fill. The community may notice a slight reduction in water levels across the year for routine planting and landscape maintenance works.
