Wyoming girds for a fight over Green, Little Snake River water
Awater fight is brewing in the West, and Wyoming water officials want to prepare for it with a study aimed at parsing and defining the state’s consumption from its Colorado River tributaries.
Anticipating a drier future and either voluntary or imposed restrictions, Wyoming should undertake a “conveyance-loss study,” Jason Mead, interim director of the Wyoming Water Development Office, told the state Water Development Commission on Oct. 6. The goal, State Engineer Brandon Gebhart told the WWDC, is to have a “defensible consumptive-use number to take to the other states,” when and if push comes to shove and Colorado River Basin water users face cuts to irrigation, industrial or municipal uses.
When Colorado River Basin water rights were divvied up starting in 1922, officials overestimated the amount of water the system would produce each year and ultimately promised more water to stakeholders than actually existed. Climate change, drought, shifting weather patterns and a population explosion in the region have exacerbated that initial over-subscription.
Further complicating the picture, the U.S. Bureau of Reclamation — the government’s Western water agency — admits there’s “an inability to exactly quantify these uses.” This “has led to various differences of opinion” regarding who gets to use how much water, the BOR states in a 2022 accounting of the river’s flows and uses.
