The health of the Ramsar-listed Hattah Lakes in the Mallee has been given an A grade rating in a Murray Darling Basin Authority report card thanks to work by the Mallee Catchment Management Authority.

The Murray Darling Basin Authority has just released its annual Living Murray Asset Report Card showing the health of Hattah Lakes improved from a C in 2013-14 to an A in 2019-20.

The improvement is thanks to environmental watering that has helped to mitigate the effects of reduced flooding due to the lack of connectivity to the Murray. Monitoring shows the watering has led to an increase in tree health, growth and reproduction.

The most recent environmental watering, delivered by Mallee Catchment Management Authority and Goulburn-Murray Water, saw 13 of the 18 Hattah Lakes wetlands covering 1310 hectares inundated with water.

The watering brought an abundance of wildlife and vital wetland vegetation back to the Hattah-Kulkyne National Park south of Mildura.

Water delivery at Hattah-Kulkyne National Park also provides great benefits for local apiarists, with conditions ideally suited for bees to rejuvenate and pollinate flowering native bush land.

The Hattah-Kulkyne National Park is culturally significant, and the Mallee Catchment Management Authority works with Parks Victoria and local Traditional Owner groups to coordinate water delivery.

A spring top-up for the wetlands is planned which will target river red gums lower on the floodplain that are in need of a drink.
