These pulses are expected to occur every few weeks and they will be short-lived and at low flow rates, with peaks of less than about 5,000 ML/day. The pulses are not aimed at transferring significant volumes of water downstream to Hume Reservoir.

With storage in Dartmouth Reservoir currently about 76% capacity, the minimum flow at Colemans can be increased from the 'normal' minimum release of 200 ML/day to an average of 400 ML/day to improve water quality.

However, ecological monitoring in the Mitta Mitta River has shown that variable flows benefit the river's health far more than constant low flows. Therefore minor pulses, which mimic natural flows, will be made from time to time which will target an average release of about 400 ML/day. Such pulses are aimed at reducing the build up of algal strands over the coming warm months.

The first of these pulses is being planned prior to Christmas and further information on all planned releases from Dartmouth Reservoir will be made available closer to the date of the release.

Landholders and river users, including pumpers, should take in to account the increase flow rates along the Mitta Mitta River and make any necessary adjustments to their river activities.
