Menindee Lakes Agreement

The changes would reduce the usual capacity of the lakes, which opponents said would result in longer periods without current in the Darling River below them. The total storage volume of Menindee Lakes at full supply is 1,731 GL, with the possibility of opening the lakes to a volume of 2,050 GL after seasonal entries. Since mid-December 2017, New South Wales has conducted emergency drought operations on the lakes, with low influx flows. The flat edges of the overflow lakes are dotted with dead black boxwood, while the banks are dominated by the grass of blue canes and sand hills. [4] The plan also aims to ensure that water is consistent throughout the basin. Some rivers and kinds of water rights were at the Ungn. the plan was not regulated, so it was necessary to introduce new rules and water-sharing agreements. The lakes were originally a series of flat natural deepenings that filled up during floods and then drained back into the Darling River. During the drought, the lakes would dry up.

The lakes are located about 110 kilometers (68 miles) southeast of Broken Hill[1] in the Sesteroid zone on gray clay and duplex soils as well as Silesic and limestone sands from the region to the far west. One of the criticisms made in the MDBA documents is that NSW provided no justification for claiming that the proposed changes to the lake humidification and drying cycle would improve the environment. The lakes are very flat and are in a hot, windy and dry area, which means that evaporation is very high. Lakes lose an average of about 400 gigalitres of water through evaporation per year. In 1963, the NSW government agreed with the Australian, Victorian and South Australian authorities that lake water could be divided to cover downstream water needs when the volume of the lakes exceeded 640 GL and until it fell below 480 GL. The Menindee Lakes are located in south-west New South Wales, on darling River, about 200 km upstream from the intersection of the Darling River and the Murray River. The town of Menindee is located near the lakes and the nearest town is Broken Hill. The lakes were originally a series of natural deepenings that filled up during floods.

When the river returned, the water flowed into the natural hollows in the Darling River. Droughts and the extent of low water can lead lakes to dry up. In the mid-20th century, changes were made to the use of lakes for water protection and regulation along the lower darling River. .
