Tod River Dam Safety Upgrade

Tod River Dam Safety Upgrade

Project Overview

The Tod River Dam is situated 27 kilometres north of Port Lincoln. It is fed from the Toolillie Creek catchment.  It is supplemented by concrete channels from the Tod River and Pillaworta creek sub-catchments.

The Tod River Reservoir was taken off-line in 2002 due to high levels of salinity. This made the water unsuitable as a drinking water supply.

The Tod River Dam will soon recieve upgrades to improve its safety.

What will the works involve?

The upgrades will be undertaken to meet updated guidelines on dam safety management.

The safety improvements will include:

  • Lowering the water level and increasing the flood capacity
  • Modifying the dam outlet to better manage the release of water
  • Modification of intake channels feeding into the Dam
  • Modifying existing causeways downstream.  Including installation of flood gauges at Gawler Ponds Road, Macdonald Road and Reservoir Drive
  • Managing sediment and erosion in the creek bed downstream of the spillway
  • Planting native vegetation for land management and sediment control

The upgrades help to ensure ongoing safety under current guidelines.

Reccent engineering and financial assessments confirmed that the planned works are the best solution. This took into account the environment and heritage costs, dam safety and community impact.

When will the works occur?

Work will begin late 2016/early 2017. The main construction will take approximately six months to complete. Revegetation works will continue until late 2017.

Will the Tod Reservoir come back online as a drinking water supply?

The reservoir was taken off-line in 2002 due to high levels of salinity. This made the water unsuitable as a drinking water supply.

Bringing the reservoir back online as a water supply network would be expensive. The safety improvements will not stop the reservoir from coming back online at a later date.
