The Winnaleah Augmentation, enhancing the existing Winnaleah Irrigation Scheme, commenced operations in May 2015 and services the Winnaleah, Derby and Herrick area in North East Tasmania.
The original Winnaleah Irrigation Scheme commenced operation in 1987. The scheme operates under self-management arrangements through an elected board of Winnaleah Irrigation Scheme Limited. Water for the scheme is collected in Frome Dam, fed by the Frome River and a diversion from the Wyniford River. A pump station is incorporated into the scheme at Toronna. The scheme now has a total capacity of 6,954 ML.
