CARSON CITY -- The second week of hearings by the state engineer into a plan to pump billions of gallons of rural Nevada groundwater to Las Vegas wrapped up on Friday, and closing arguments were scheduled for Monday.

Friday's session on the Southern Nevada Water Authority's bid to get more than 90,000 acre-feet of water from Spring Valley, near the Utah border in White Pine County, included a caution against overpumping from prominent water expert John Bredehoeft.

Bredehoeft, a consultant who worked for the U.S. Geological Survey for 32 years, noted that both the USGS and hydrologist Tom Meyers did studies indicating the water authority's pumping would produce large drawdowns that would hurt Spring Valley water users.

Also testifying was White Pine County Commissioner Gary Perea, who said advocates of the water pumping are "blinded by greed" and shouldn't be allowed to take a resource that his county needs for its future growth.

The water authority contends that the amount of water that can be safely pumped on an annual basis from the valley is about 100,000 acre-feet -- more than what it's seeking.

But Meyers testified Thursday that the plan would damage existing water rights that already total more than 70,000 acre-feet per year.

The Spring Valley plan is a main element of a $2 billion plan to send more than 180,000 acre-feet of water a year from rural valleys to Southern Nevada.

The water authority is seeking state approval for 19 groundwater applications it filed in Spring Valley in 1989.
