Yanco Weir is a heritage-listed weir at Yanco, Leeton Shire, New South Wales, Australia. It was built from 1928 to 1929 by WC & IC. It is also known as Yanco Weir and site. The property is owned by Department of Planning and Infrastructure, a department of the Government of New South Wales. It was added to the New South Wales State Heritage Register on 2 April 1999.
History
The 1929 Yanco Weir was built 1928-9 to divert flows from the Murrumbidgee River to the Yanko, Colombo and Billabong Creeks System for irrigation. In 1980 the Weir was reconstructed and its diversion capacity was enlarged to 290,000 megalitres (10,000×106 cu ft) per year. This increased capacity has resulted in significant increase in irrigation development along the creek system. c. 1980, a new weir was erected nearby at the diversion, and the 1929 weir was concreted over. The 1929 weir is now not in operation. The site of the 1929 weir contains many remnants of early structure.
Description
The 1929 Yanco Weir is located approximately 14 kilometres (8.7 mi) downstream of Narrandera. The Weir measures 75.59 metres (248.0 ft) between abutments. It consists of concrete sill floor surmounted by several concrete piers of about 3.58 metres (11.7 ft) high. The concrete sill floor, originally reinforced with timber piles and sheet pilings, has been further reinforced with concrete piles and sheet piling during the 1980 reconstruction. The weir has been concreted over due to the commencement in usage of the new weir constructed nearby. The immediate grounds of the 1929 weir contain evidence of early usage, with remnants of many early structures such as the poles used for manual operation of the weir gates, scales showing past flood water level, etc.
Modifications and dates
Concreted over c. 1980. No longer in use.
Further information
Preparation of a Conservation Management Plan for weir and grounds, including all remnants and evidence of early usage is highly recommended.
Heritage listing
As at 8 December 2000, the 1929 Yanco Weir is one of the earliest weirs built on the Murrumbidgee River to regulate the flow of water to the Murrumbidgee Irrigation Area. It is associated with the historical development of the area and provides a good source for interpretation of the changing needs of the irrigation system. The site contains many remnants of early structures related to the early weir.
Yanco Weir was listed on the New South Wales State Heritage Register on 2 April 1999 having satisfied the following criteria.
The place is important in demonstrating the course, or pattern, of cultural or natural history in New South Wales.
