COMMONWEALTH and state agencies co-ordinate on every release of environmental flows in the Murray and Goulburn valleys to gain the greatest benefit, according to a Federal Department of Agriculture, Water and the Environment spokesperson.

The spokesperson was responding to criticism by deputy mayor Bill Moar at last week's Swan Hill Rural City Council meeting that there was a lack of co-ordination between the authorities managing environmental water.

Cr Moar's comments came during discussion of a proposal from Cr Nicole McKay that the council ask for a boost to environmental flows.
