The issue went to court because Diamond Valley, in Eureka County, is dramatically over-appropriated and has been pumped at a rate exceeding its annual recharge for more than four decades. The opinion authored by Justice Jim Hardesty says 76,000 acre-feet of water is pumped from the valley every year but the aquifer can only support 30,000 acre-feet of annual pumping. As a result, Diamond Valley has been designated a critical management area, which gives the state engineer the power to impose a management plan on users.
