South Para Reservoir

South Para Reservoir is the second largest reservoir in South Australia, behind Mount Bold Reservoir, and the principal reservoir of the South Para River system. The reservoir's large capacity of around 45,330 megalitres and its location in the catchment area mean that it only ever fills completely once in every five years.

Costing A$6.4 million, the reservoir took almost a decade to construct, between 1949 and 1958, due to a demand on resources in the post-war boom. The building of the historic Mannum–Adelaide pipeline from the River Murray to the water-short city of Adelaide was a key delay in South Para's construction; that pipeline today disperses water into the reservoir.
