The Colorado River, a vital water source for the Southwestern United States, is facing a looming water crisis. Since 2000, the volume of the river has decreased by a staggering 19%, and experts predict that it could decrease by 30% by 2050 if temperatures continue to rise.
One of the major contributors to the decline in water levels is the excessive use of the river’s water for agricultural irrigation. More than half of the Colorado River’s water is used for this purpose, with alfalfa and grass hay for cattle feed alone accounting for a third of the water usage.
The consequences of this overconsumption are evident – the Colorado River’s water hasn’t reached its delta in the Gulf of California for over 50 years due to the high levels of agricultural consumption upstream. This has prompted negotiations between lower-basin states to come up with a plan to conserve water from the Colorado River, as legal agreements regarding water usage are set to expire in 2026.
The Bureau of Reclamation is responsible for tracking water in the river system, but there are large portions, such as the Gila River Basin in Arizona, that were not included in the 1922 Colorado River Compact. Mexico currently uses 7% of the total Colorado River water supply, while the Gila River Basin consumes 9%.
Farmers who rely on the Colorado River for irrigation may soon face the tough reality of having to reduce their water use by 20% to adapt to the decreasing water availability. Drought, overconsumption, and climate change are all contributing factors to the diminishing water volume in the Colorado River.
As the clock ticks on this impending water crisis, stakeholders must come together to find sustainable solutions to ensure the longevity of this crucial water source for generations to come.
