Sullivan v. Lincoln County Water District
Annotate this Case
In this case, the Supreme Court of the State of Nevada considered whether the Nevada State Engineer had the authority to combine multiple existing hydrographic basins into one "superbasin" for the purposes of water administration and management based on a shared source of water. The State Engineer had combined seven basins into one superbasin, the Lower White River Flow System (LWRFS), after determining that the waters of these basins were interconnected such that withdrawals from one basin affected the amount of water in the other basins. The State Engineer also found that the previously granted appropriations of water exceeded the rate of recharge in the LWRFS. Various entities who owned water rights throughout the new superbasin challenged the State Engineer's decision, claiming that he lacked the authority to manage surface waters and groundwater jointly and that his decision violated their due process rights.
The Supreme Court of the State of Nevada held that the State Engineer indeed had the authority to manage surface waters and groundwater conjunctively and to jointly administer multiple basins. The court also found that the State Engineer did not violate the rights holders' due process rights because they received notice and had an opportunity to be heard. The court reversed the lower court's decision that had granted the rights holders' petitions for judicial review and remanded the matter back to the lower court for further proceedings to determine whether substantial evidence supported the State Engineer's factual determinations.
