Recreation areas at SCA's dams will be closed on all Total Fire Ban days.
Cataract, Cordeaux, Avon and Nepean Dams are all located south of Sydney. The Upper Nepean dams were built in the early 1900s to meet Sydney's growing water needs. Featuring architecture and engineering typical of the time, and situated in beautiful bushland settings, the dams are an excellent day trip destination.
The facilities at these grounds include:
- Viewing areas
- Picnic shelters
- Electric barbecues
- Toilets/disabled toilets
- Drinking water
- 10am to 5pm daily (during daylight saving hours the dam will remain open until 7pm on weekends and public holidays)
- The dams are open every day of the year
- Please note: There is no entry to any of the dams 15 minutes prior to closing time. Access to some SCA areas may be restricted from time-to-time due to construction or operational activity, or for environmental reasons
To help the Sydney Catchment Authority (SCA) manage its picnic facilities, please notify us in advance when the size of groups visiting any of our sites will exceed 50 visitors. This can be done using the large group notification form.
