When you are visiting Mildura, you may notice a number of holiday houseboats moseying down the Murray River. A fascinating look at the how and why that makes all of this now possible can be attributed to a series of locks and weirs used to control the flow of water, the most notable being Lock 11. Before this irrigation system, the Murray River was fairly unreliable, either flooding the area or leaving it completely dry. As the river became more important to the development of the town, in 1927 the construction of Lock 11 was completed to help regulate the flow of water.
Visitors come to see Lock 11 and its construction of four steel lock gates along with a concrete chamber. Water flows through and is locked off upstream, regulating how much water flows through the river. Now, its existence has formed an entire way of living in Mildura paving the way for houseboats, water sport activities, and paddleboats year-round.
