Landholders and river users, including pumpers, on the Mitta Mitta River are advised to take into account the forecast releases of water from Dartmouth Dam and make any necessary adjustment to their river activities.

In the coming days, the release from Dartmouth is expected to increase as additional water is transferred from Dartmouth to Hume Dam ahead of increasing downstream system demands.

MDBA operations planning has indicated the continued need to draw on water from Dartmouth in September and beyond if conditions remain dry. For September, MDBA releases from Dartmouth will fluctuate up to 7,000 ML/day. These release rates aim to transfer appropriate volumes to Hume, whilst limiting erosion along the Mitta Mitta River.

These varied releases better align with the natural variability of the lower Mitta Mitta River and are environmentally preferable to maintaining steady flows.

Releases will be adjusted if significant rainfall occurs in the catchment downstream of Dartmouth. Without rainfall, river heights at Tallandoon are expected to remain below 3.1 m (~7,800 ML/day), below channel capacity.

System conditions may change over the coming weeks and months. Another flow advice will be issued once MDBA operations planning indicates an increased or decreased need to transfer water from Dartmouth to Hume.

Landholders and river users on the Mitta Mitta are advised to regularly check the current flows and forecasts on the MDBA website for more information on releases from Dartmouth Dam. Summary information about the River Murray system is available in the River Murray weekly report.
