TASWATER will shortly begin lowering the water level in Risdon Brook Dam as part of a planned maintenance program.
It will involve the removal of vegetation from within the dam, which will help improve the water quality.
This work will take place over several weeks, with part of the walking track briefly closed while heavy machinery is moved into place.
This will mean that for short periods, access to the walking track loop around the dam may be restricted for safety reasons.
These works will only take place during business hours and not weekends.
The water will be lowered in a slow and controlled manner through a valve which will allow it to flow into the adjacent Risdon Brook waterway, next to the East Derwent Highway.
Flows in the brook may be slightly higher than usual, but will not affect the surrounding area.
The water level in Risdon Brook Dam is already quite low due to ongoing dry conditions.
With further lowering, significant areas of the dam will be exposed which is likely to alter the look of the shoreline.
Risdon Brook Dam is a back-up drinking water supply for the Eastern Shore, which is normally used over the dry summer months when demand increases.
Scheduling the works at this time of year gives TasWater time to refill the dam before next summer when it may next be needed.
TasWater appreciates the patience of visitors to Risdon Brook Dam during the work periods but when it is finished, the dam is expected to be returned to its usual level with access to the walking trail fully restored.
