Question: Rewrite the paragraph "The Walker River Basin (WRB) largely in Nevada, USA, exemplifies basins with a thriving upstream agricultural sector and a degrading terminus lake due to decades of upstream agricultural diversions and groundwater pumping. The basin's water rights system is based on the prior appropriation doctrine, granting priority to the earliest water users, mostly agricultural users for beneficial use. Governed largely by the Walker River Decree, water rights define allocation mainly for agricultural purposes. While most groundwater pumping supplement decree water rights, groundwater pumping has been unsustainable for decades with declining water levels (Carroll et al., 2016, Davies and Naranjo, 2022, NDWR, 2022).
