Seqwater advises Leslie Harrison Dam is releasing water into Tingalpa Creek via the siphon system.
These releases are to reduce storage levels in the lake while the Leslie Harrison Dam spillway repair works are underway. Flows will increase down Tingalpa Creek.
If you are downstream of the dam, please avoid potential hazards such as fast flowing or deep water near waterways and floodplains.
