State Attorney General Mike Hilgers and Governor Jim Pillen announced Wednesday that Nebraska is suing Colorado over South Platte River water rights.
The announcement was made at the State Capitol along with multiple managers of natural resource districts in western Nebraska.
At issue is the South Platte River Compact, signed by the two states in 1923.
Nebraska is arguing that Colorado is taking more than its fair share of water as laid out in the contract and is obstructing the construction of the planned Perkins County Canal.
The two states were last at odds in the nation’s highest court back in 2016, when Nebraska’s challenge to Colorado’s then-new recreational marijuana law was shot down.
Colorado has not yet responded to this newest suit, but state leaders have in the past dismissed Nebraska’s concerns as invalid.
