Ross Creek Reservoir Dam Project

The Ross Creek Reservoir dam project is part of the city’s Security of Supply Strategy to ensure the city has water supply options if problems arise getting water from Dunedin’s main water sources at Deep Creek and Deep Stream.

Ross Creek Reservoir

Work to strengthen and repair the Ross Creek Reservoir Dam embankment, in one of the city’s most popular recreation areas, is underway.

The Ross Creek Reservoir, which was opened in 1867 (with something of an anti-climax due to a break in the water main), has not been used for about 20 years. It is the oldest large earth dam in the country, and has Historic Places Trust category one status, but is in poor condition and needs attention to ensure its ongoing safety. Since large cracks appeared in 2010, the dam has been closely monitored with an irrigation system installed on the dam face and gradual lowering of the water level to prevent further instability.

The Ross Creek Reservoir dam project is part of the city’s Security of Supply Strategy to ensure the city has water supply options if problems arise getting water from Dunedin’s main water sources at Deep Creek and Deep Stream. Once these projects are complete, the reservoir’s storage capacity of 130,000m3 can be used again and water supply could be maintained to the entire city if the Deep Creek/Deep Stream pipelines were lost.

The projects that make up this strategy represent considerably better value than those proposed and budgeted for in previous Long Term Plans. In total, the strategy should deliver savings of up to $11.2 million between 2012 and 2022.
