Fact sheet New Dungowan Dam waternsw.com.au Background WaterNSW has released a 20-year infrastructure options study for rural river valleys which addresses future challenges in operating regulated river systems. The objective of the study was to guide water infrastructure investment by all levels of government. Prime Minister Scott Morrison and NSW Premier Gladys Berejiklian have announced a jointly funded package of around $1.1bn for the planning and delivery of three new or augmented dams in NSW. This includes the replacement of the existing Dungowan Dam near Tamworth. Replacing the current Dungowan Dam with a new, larger dam will improve water availability and security in the Peel Valley. The Peel Valley supports Tamworth and other smaller townships, as well as irrigated agriculture and industry. The principle objective of the Dungowan Dam project is to secure the long-term water supply security for the regional city of Tamworth. Further, the project will enable future population growth for Tamworth, which together with an already-augmented Chaffey Dam will maintain a productive level of general security reliability and water use for irrigation. Over time, this objective is expected to underpin water affordability that will support broader agricultural productivity benefits for the region.

Background
WaterNSW has released a 20-year infrastructure options study for rural river valleys which addresses future challenges in operating regulated river systems. The objective of the study was to guide water infrastructure investment by all levels of government.
Prime Minister Scott Morrison and NSW Premier Gladys Berejiklian have announced a jointly funded package of around $1.1bn for the planning and delivery of three new or augmented dams in NSW. This includes the replacement of the existing Dungowan Dam near Tamworth.
Replacing the current Dungowan Dam with a new, larger dam will improve water availability and security in the Peel Valley.
The Peel Valley supports Tamworth and other smaller townships, as well as irrigated agriculture and industry.
