The Northern Midlands Irrigation Scheme (NMIS) provides high-surety irrigation water to Macquarie, Barton, Conara, Campbell Town, Ross and the Lower Isis Valley areas in central Tasmania. The NMIS provides additional irrigation water that is underpinned by large Hydro Tasmania storages in the central highlands of Tasmania. The scheme has an offtake dam and pump station below the Poatina Power Station and pipes water to Conara, Campbell Town and Ross with two boost pump stations and two balance tanks.
The construction phase has recently been completed, and water is now available for the 2026/2027 summer irrigation season
