Lyon County commissioners recommend denying Walker Basin Conservancy water-right changes after irrigation district protest

On Oct. 2, 2025, the Lyon County Board of County Commissioners voted unanimously to recommend that the Nevada state engineer deny eight change applications filed by the Walker Basin Conservancy to alter points of diversion and places and manner of use for water appropriated under the Walker River decree.

The recommendation followed a protest filed by the Walker River Irrigation District, which argued the proposed changes would threaten domestic wells, raise water costs for other rights holders and reduce delivery efficiency. That protest covers multiple change applications affecting land in Smith and Mason valleys; the conservancy’s request involves about 4,727 acres and 60.975 cubic feet per second of natural flow, which the county manager provided staff calculations for as roughly 1,770 acre-feet.

District Attorney Steve Rye summarized the irrigation district’s protest during the meeting and recommended the board act in deference to the district’s concerns. “I believe staff recommendation at this time would be that the board recommend denial of this application until this protest can be resolved,” Rye said. He noted the applications are complex and involve multiple moving parts that could affect domestic users and irrigation delivery in the Walker River system.

Commissioners discussed the county’s role and limits: the board’s action is a recommendation to the state engineer and is not binding. County Manager Andrew Haskin confirmed county staff received notice because some of the affected water is used in Lyon County through an interconnect with Carson City. Commissioner Jacobson asked whether the change equated to about 1,770 acre-feet; county staff confirmed that figure was in the materials provided.

Public comment at the meeting included a caller who said local water users have already lost water and urged denial. After discussion, Commissioner Hockaday moved to recommend denial and to have the county manager prepare a letter detailing the board’s decision and reasons; Commissioner Hendricks seconded. The motion passed, 5-0.

The board’s recommendation will be forwarded to the state engineer for consideration under the statutory change-of-use process. The state engineer’s final decision may differ from the county’s recommendation; commissioners and staff said they expect follow-up as the protest is resolved.
