Through much of the 1990s, Kansas and Nebraska argued in court over water usage, with the dispute being settled in 2002 and the U.S. Supreme Court adopting the settlement as a court order, Barfield said. The first measure of Nebraska’s compliance, Barfield said, was in 2005 and 2006. “Nebraska used 80,000 acre-feet more than allowed,” Barfield said; that’s roughly the amount of water a city of 100,000 would use over 10 years.

Kansas officials have been trying to bring groundwater pumping along the river in Nebraska under control. Past agreements were aimed at letting states monitor and control water use to comply with the 1942 compact, which allotted 300,000 acre-feet a year for Nebraska, 240,000 acre-feet a year for Kansas and 40,000 acre-feet a year for Colorado. Kansas officials argue that Kansas is losing 16 percent of its water under the compact.
