The Tod Reservoir is located on the Eyre Peninsula in South Australia, in the localities of Whites Flat and Koppio, 27 km north of Port Lincoln.

[4] A museum which features audio and visual displays is located off White Flat Road, northwest of Poonindie.

[1] The catchment yield for the Tod River is estimated to be 11 gigalitres per annum, though this can reduce significantly during periods of drought.

Reasons for the change include increasing salinity and concerns about the levels of agricultural chemicals in the reservoir.

SA Water investigated this option and concluded it was not viable because of the difficulty in finding an environmentally suitable location for brine waste disposal.

Alternative views exist, with others suggesting that desalination could be viable with some further engineering and catchment management considerations.
