Our water supply

Flow and consumption


Where does our water come from? 


The main water supply (other than the village systems of Wooli and Minnie Water) in the Clarence Valley is sourced from the pristine Nymboida River, part of the Clarence River catchment area. The Nymboida River also gravity feeds water to Shannon Creek Dam when required.

If the Nymboida River can't be used as source water due to low flow (less than 225 Megalitres a day) or because the turbidity is too high after a wet weather event, our water is sourced from the off-stream storage of Shannon Creek Dam. Overall, Shannon Creek Dam is used to supply the Clarence Valley’s water about 5% of the time.

Shannon Creek Dam is located in the Clarence Valley Local Government Area and is a part of the Regional Water Supply Scheme that links the Clarence Valley and Coffs Harbour bulk water supplies. It is a great place to visit with car parking, information boards and a viewing area at top of the dam wall. It is open to the public Thursday to Sunday except for Good Friday and Christmas Day. However it's a good idea to check with Clarence Valley Council prior to your trip as the dam may be shut from time to time for operational or public safety reasons, for example in the event of a bushfire.
