Dial Blythe Irrigation Scheme
Tranche One

Close to processing facilities and mainland marketing opportunities, the climate, high quality soils and reliable irrigation of the Dial Blythe area make it one of the most productive regions in the state

The Dial Blythe Irrigation Scheme commenced operations in May 2015 and services the Penguin, West Pine, South Riana, Cuprona and Howth areas in North West Tasmania. Irrigation water is sourced from inflows into the 4,000 ML South Riana Dam and supplemented by water pumped from the Blythe River. The dam is located on an unnamed tributary of the Blythe River near South Riana.

The dam is filled during winter months and can be topped up during summer. Delivery throughout the district is via 43.6 kms of pipeline, with water being pressurised at the South Riana Dam Pump Station.
