GORGE WEIR (LEICHHARDT) ON BURDEKIN RIVER - OPENED 6TH DECEMBER 1953

Towards the end of World War II, Australia sought to expand agricultural land for returning soldiers. In the Lower Burdekin region, efforts began to develop farmland, especially for tobacco, which had been grown in Home Hill since 1909 by pioneers like Richard Bayliss.
By 1948, land was being sold around Clare for tobacco cultivation, but water availability was a significant challenge. To address this, a weir was planned at the Gorge in the Leichhardt Ranges, upstream from the confluence of the Bowen and Burdekin Rivers. This weir would support the new agricultural settlements of Clare, Millaroo, and Dalbeg.
Construction of the weir, located about 80 miles from Ayr, began in July 1952, with roads and bridges being built to access the site. By August, the first concrete had been poured for a temporary weir. The project involved a substantial workforce, and by November 1952, detailed surveys and contour plans for the diversion dam were completed.
The dam was designed to store 6,600 acre-feet of water for use in the first stage of the development. The worksite employed around 100 men, and 53 tobacco farms were established in Clare, with additional farms planned once the weir was completed.
The project, overseen by Alf T. Taylor of the Irrigation and Water Supply Commission, faced challenges, including a crane accident on June 30, 1953. The accident seriously injured two workers, Reginald William Buckley and Lewis Chaffey, requiring a 160-mile round trip to the hospital. Despite setbacks, the weir was completed by November 4, 1953.
On December 6, 1953, the Gorge Weir was officially opened by the Minister for Lands and Irrigation, the Honourable T. A. Foley, alongside other dignitaries. The event attracted a large crowd from the Lower Burdekin District. After the opening, guests inspected the Millaroo Irrigation Pumping Station, which was still under construction, and then visited the township of Millaroo for afternoon tea.
The Gorge Weir, a gravity-type structure built at the mouth of the Gorge in the Leichhardt Ranges, measured 1,320 feet wide and varied in height up to 40 feet due to the uneven rock foundation. The weir included a section of hardwood drop-boards that were removable and allowed water to back up about six miles, storing approximately 6,600 acre-feet. Water was released through an 8-foot wide by 4-foot high gate to flow down to the pumping stations at Clare, Millaroo, and Dalbeg, which became operational in 1954-55. The weir's construction cost approximately £400,000, which was £91,000 below the original estimate.
The Gorge Weir was part of a broader plan outlined in the Burdekin River Irrigation Hydro-Electric and Flood Mitigation Project Report of December 1951 by the Burdekin River Authority.
This plan included several stages: Stage 1, which was the construction of the Gorge Weir; Stage 2, the building of the Burdekin Dam at the Burdekin Falls, completed between 1984 and 1987; Stage 3, the proposed raising of the Burdekin Dam to enable water recycling and hydroelectricity generation, which remains unfulfilled as of 2022; and Stage 4, the construction of the Leichhardt Diversionary Dam downstream of the Gorge Weir, which was intended to open up agricultural land on the east bank of the Burdekin River and divert water towards Bowen. However, Stage 4 was never realized.
Today, the Gorge Weir has been supplemented by the Clare Weir and a pumping station at Steepy Banks on the Burdekin River, which channels water into the Upper Haughton River and ultimately contributes to Townsville's water supply. The Gorge Weir, a key component of the region's agricultural development, remains a significant historical and engineering landmark.
