Шаблон:Use Australian English Шаблон:Use dmy dates Шаблон:Infobox dam The Burdekin Falls Dam, also known as the Burdekin Dam, is a concrete gravity dam with an uncontrolled spillway across the Burdekin River in the Whitsunday Region, Queensland, Australia. Built for the purpose of irrigation, the reservoir is called Lake Dalrymple, and is on the boundary of the Whitsunday Region and the Charters Towers Region. Burdekin Falls Dam is managed by SunWater. Water from the reservoir is also used to replenish downstream aquifers.

Location and features

The dam wall is Шаблон:Convert long and has a Шаблон:Convert spillway, and a drop of Шаблон:Convert. The reservoir holds Шаблон:Convert at full capacity. The design allows for future storage capacity increases and potential for hydro-electricity generation. Шаблон:As of, plans are in place to increase the safety of this dam in an extreme rainfall event by raising the spillway height by Шаблон:Convert increasing the storage capacity of the dam by Шаблон:Convert or 31 per cent.

The catchment area for the dam extends north to the Seaview Range west of Ingham, south to the Drummond Range near Alpha through the Suttor and Belyando Rivers, southeast to the coastal ranges west of Mackay, and west beyond Charters Towers to the Lolworth, Montgomery and Stopem Blockem Ranges through the Clarke River.

History

Construction of the dam began in 1984. It was completed by Leighton Contractors in 1987 and is the largest lake in the state, with a capacity four times that of Sydney Harbour. The lake filled after the wet season in 1988.

Irrigation

The Burdekin River Irrigation Area was granted approval in 1980. It is Queensland's largest land and water conservation scheme. In 2007, the scheme was supplying Шаблон:Convert of land located about Шаблон:Convert inland from Townsville with water to grow a range of crops including sugarcane, cotton and rice.

Proposed hydroelectricity

Water discharging at Burdekin Dam's spillway

In 2012, Stanwell Corporation undertook a feasibility study into a proposed Шаблон:Convert hydroelectric power station below the dam wall. It was proposed it would be capable of producing Шаблон:Convert annually, enough to power more than 9,500 homes each year. As at November 2023, construction was scheduled to commence in 2025 and be operational in 2027 producing Шаблон:Convert.

Boating

There are no boating restrictions, with a single boat ramp located near the dam wall. Water in the lake is often muddied with unsettled sediment long after the rains have washed it into the lake. This not only makes angling difficult but also means boating can be hazardous at high speeds due to the presence of submerged rocks.

Fauna and flora

The lake has been stocked with sleepy cod, sooty grunter and barramundi. Numerous other species are present naturally, including forktail catfish, spangled perch, eel-tailed catfish, long tom, golden perch and archer fish. A Stocked Impoundment Permit is required to fish in the dam. Red-claw crayfish and freshwater crocodiles although not native to this river may also found in the lake. These were probably released by people who caught them from rivers of the Gulf of Carpentaria. Saltwater crocodiles are commonly known to take cattle from the reaches of both Burdekin and Suttor river sections of Lake Dalrymple reaches of the dam.

Awards

In 2009 as part of the Q150 celebrations, the Burdekin Falls Dam was announced as one of the Q150 Icons of Queensland for its role as a "structure and engineering feat".
