In June 2011, a federal parliamentary committee (chaired by independent Tony Windsor) delivered its report to MDBA and its recommendations on water cutbacks in the basin. The committee was told river communities faced annihilation if 4,000 gigalitres was returned to the environment. The committee also reported that the health of the river system could be protected without the cuts. The Australian Conservation Foundation said it was disappointed by the report delivered by the inquiry into the Murray-Darling river system. The Foundation believed that buybacks were the most efficient way to save the basin.
