The debate continues on the prior appropriation system. During the 2016 Family Farm Alliance Annual Conference, the Alliance’s 2015 report on the prior appropriation doctrine raised some debate. This debate, now focusing on Nevada’s prior appropriation system, was again raised in equal vigor during the 2016 Nevada Water Resources Association annual conference. While many argue the system fundamentally works, some commenters took the stance that the prior appropriation doctrine was flawed and should be reconsidered.
One alternative suggestion presented during these discussions was to adopt the Australian Model which changes a water right to a water share, and strives to entitle these water license holders to a specific share in the available water and to take water at specific times, rates or extraction points. However a true understanding of prior appropriation provides for water use under these circumstances, with the main difference being, in a short water year, the difference class of shareholders receive different allocations. So instead of a month, day and year priority to govern who receives their water first, the Australian Model groups all users into classes of shares with perhaps 3-5 classes all together depending on the stream system. What we did not hear about was how the Australian system handles conjunctive management calls within these class-share systems.
We suspect this debate will continue throughout the western United States as climate change and the drought continue.
