The Murray River, at 2,508 kilometres (1,558 mi) in length, is Australia's longest river. The Murray rises in the Australian Alps, draining the western side of Australia's highest mountains. Overall the catchment area is one seventh of Australia's total land mass. For most of its length, it meanders across Australia's inland plains, forming the border between the states of New South Wales and Victoria as it flows to the northwest. It then turns south for about 500 kilometres (310 mi) into South Australia, then reaching the ocean at Lake Alexandrina. It is perhaps Australia's most important irrigated region, and it is widely known as the food bowl of the nation.
Share the best of the outdoor life of the vibrant Murray River region. Stroll along sandy river beaches, wander through towering red gum forests, or take a cruise downriver on a paddle steamer or canoe. The Murray River region is full of striking natural landscapes and winding waterways. The Murray-Darling provides a wonderful outlet for swimming, boating, fishing, kayaking and house boating.
Of the numerous locks that were proposed for The Murray, only 13 were completed. Locks 1 to 11 on the stretch downstream of Mildura, Lock 15 at Euston and Lock 26 at Torrumbarry. Construction of the remaining weirs purely for navigation purposes was abandoned in 1934. The last lock to be completed was Lock 15, in 1937. Lock 11, just downstream of Mildura, creates a 100-kilometre (62 mi) long lock pool which aided irrigation pumping from Mildura and Red Cliffs. Each lock has a navigable passage next to it through the weir, which is opened during periods of high river flow, when there is too much water for the lock. The weirs can be completely removed, and the locks completely covered by water during flood conditions. Lock 11 is unique in that the lock was built inside a bend of the river, with the weir in the bend itself. A channel was dug to the lock, creating an island between it and the weir.
