The skies were heavily overcast as we departed Sydney and flew direct to Burrendong Dam, the first wetland in this part of Survey Band 4.

The weather had cleared a little west of Bathurst, so we were able to proceed unhindered. Burrendong Dam is currently at 130% capacity and the spillway was a spectacle as the waters roared out into the Macquarie River. There were only a few cormorants on the dam.

After refuelling at Dubbo we continued west, travelling north of the Lachlan and near Mt Hope and Yathong Nature Reserve in mallee country. The landscape was far greener than we had ever seen it. Surprisingly, the Talyawalka Lakes were mostly dry, with only one, Teryaweynya Lake holding water and supporting low numbers of waterbirds and a small colony of around 300 Pied cormorants.

We headed a little further west along Band 4 to the Menindee Lakes system. Most of the large lakes in the system were completely full, with waterbirds widely dispersed across large areas of open water. The most numerous waterbirds were pelicans, cormorants and darters, followed by occasional herons, spoonbill and egrets.

We spent several hours covering this almost full lake system and with the sun setting we headed into Broken Hill for a late finish.
