Highlights

Activities

Delivery of water for the environment to Lake Kramen provided a much-needed drink for stressed trees and attracted large flocks of regent parrots. (Photo: Mallee CMA)

Community

As part of the National Waterbug Blitz citizen scientists learned how to undertake waterbug sampling at Lake Kramen. Results from these blitzes help assess the health of our local waterways. (Photo: Mallee CMA)

Vegetation

Planned drying of the main Hattah Lakes resulted in damp lakebeds. This creates ideal conditions for a rich diversity of wetland and floodplain plants to germinate, grow and thrive. (Photo: Mallee CMA)

Waterbirds

Shallow edges of the drying lakes exposed excellent foraging habitat for birds. Flocks of red-necked avocet, sharp-tailed sandpipers and pied stilt were observed feeding. (Photo: Mallee CMA)

Fish

A planned drying of the main Hattah Lakes was undertaken to control carp. This is to prepare the lakes for future water for the environment delivery and improve the likelihood of native fish recolonising the lakes. (Photo: Mallee CMA)

Each year, water is released into the environment depending on the climatic conditions. See the outcomes of water over time for a long-term view of how natural and released water affects the health of rivers.
