South Para Reservoir Modification
Modifications to the South Para Reservoir dam wall and spillway are proposed that will increase the mitigation capability of the reservoir. This will have the affect of reducing the flow in the Gawler River for major storm events.
The proposal is to raise the dam wall by 1.0 metre and raise the spillway by 1.57 metres but include a 10 metre wide slot. These modifications would have the effect of constructing a flood control storage on top of the full storage level of the reservoir. A paper presented to the ANCOLD 2005 Conference that describes a risk assessment approach to upgrading the reservoir and undertaking the proposed modifications can be downloaded from this page. Construction of these works will be undertaken at a cost to the Scheme by SA Water, possibly in conjunction with dam safety upgrading, and is planned to be completed by July 2010.
