Water in the Shoalhaven largely comes from the Shoalhaven River however Shoalhaven Water own and maintain 3 large storage dams. These dams are used to store water before being processed and pumped throughout the city to the residents and visitors.
Our water network consists of 38 water reservoirs, 26 pumping stations and over 1,500 kilometres of water mains.
Bamarang Dam is located west of Nowra and has a total capacity of 3,800 ML. This dam is known as an off-creek storage dam and water is pumped into it from the Shoalhaven River before being transferred to the Bamarang Water Treatment Plant for processing.
Bamarang Dam is only topped up from the river while river flows are running at a flow rate above 90ML per day. During times of drought when the river flows are very low, we cease pumping and rely on the water stored in the dam.
Reduced water levels in this dam are a trigger for water restrictions and it is during these times that we as a community must become more water conscious.
For more information on why water restrictions are brought into place visit our Water Snapshot page.
Danjera Dam is located in a catchment area west of Nowra and has a total capacity of 7,660 ML. The water stored in this dam is our backup water supply and water is only released from this dam as a result of water restrictions.
Although remote, this is a popular camping area. For more information follow this link Danjera Dam Camping Area.
Porters Creek Dam
Porters Creek Dam is located in the southern Shoalhaven in Morton National Park, around 11km west of Lake Conjola. It has a total capacity of 1,900 ML and depending on water levels, this dam supplies water to the southern end of the Shoalhaven. The water from this dam is treated at the Milton Water Treatment Plant.
NOTE: ML = megalitres = 1,000,000 litres
