Yanco Weir

Yanco Weir is a heritage-listed weir located in Yanco, New South Wales, Australia.

It was built in 1928-1929 to divert water from the Murrumbidgee River for irrigation purposes. The property is owned by the Department of Planning and Infrastructure, and it was added to the New South Wales State Heritage Register in 1999.

The construction of Yanco Weir in 1928-1929 played a significant role in the history of irrigation. It regulated the flow of water to the Murrumbidgee Irrigation Area and contributed to the development of irrigation along the creek system. The weir was reconstructed in 1980, increasing its diversion capacity to 290,000 megalitres per year. The site of the 1929 weir contains remnants of the early structure, making it historically significant.

Yanco Weir is located approximately 14 kilometers downstream from Narrandera. It measures 75.59 meters between abutments and consists of a concrete sill floor with concrete piers. The 1929 weir, which is no longer in operation, was concreted over due to the construction of a new weir. Remnants of early structures, such as poles and flood-level water scales, can be seen in the immediate surroundings of the 1929 weir.

Yanco Weir holds great heritage significance as one of the earliest weirs on the Murrumbidgee River. It played a crucial role in supporting irrigation in the area and represents the changing needs of the irrigation system. The surrounding land has been developed for tourism and recreation, offering an aesthetically pleasing environment. The heritage listing on the New South Wales State Heritage Register recognizes the social, cultural, and spiritual
