The state's top water regulator has decided to join the Southern Nevada Water Authority in an appeal of a recent court ruling that dealt a blow to the authority's plans to tap groundwater in three Lincoln County valleys.
Spokesman Bob Conrad said the state engineer's office will file its notice of appeal with the Nevada Supreme Court today.
At issue is District Judge Norman Robison's decision to strike down a 2008 order from State Engineer Tracy Taylor that cleared the authority to pump more than 6 billion gallons of groundwater a year from Cave, Delamar and Dry Lake valleys in central Lincoln County.
Those three watersheds represent the first phase of the authority's proposal to one day tap groundwater from as far as 250 miles away in White Pine County and pipe it south to supplement Las Vegas amid drought on the Colorado River.
The water authority board on Thursday voted to appeal Robison's Oct. 15 ruling.
Chuck Hauser, general counsel for the authority, said it could take a year or more for the state Supreme Court to hear the appeal.
