The planned draining of Kangaroo Creek Reservoir has revealed the original Gorge Road and Batchelor’s Bridge.

SA Water’s Mark Gobbie said the dam was drained as part of a $94 million project to disaster proof the reservoir.

“We’ve gradually lowered the reservoir’s water level over the past few months, with releases supporting dilution flows into the Torrens, or fed into the Hope Valley Reservoir for drinking water supply,” Mark said.

“The reservoir will be kept at zero for around six weeks, while we install approximately 1000 metres of external seals on the upstream face joints of the dam embankment.

“Natural inflows will likely fill the reservoir again over the next year or two, while work continues on the other side of the embankment, widening its base with 180 000 of the 300 000 cubic metres of rock blasted from the spillway.”
