The Boort wetlands are on the floodplain to the west of the Loddon River, downstream of Loddon Weir. They consist of Lake Boort, Lake Leaghur, Lake Yando and the Meran Lakes complex of wetlands. Several other wetlands occur in the district but are currently not managed with environmental water.
The natural water regimes of wetlands in the Loddon system have been substantially modified by the construction of levees and channels across the floodplain and by the construction and operation of reservoirs and weirs along the Loddon River. Environmental watering in the Boort wetlands aims to manage wet and dry phases to improve environmental condition and habitat value.
