What is the problem with the Colorado River?
Drought has been parching the Colorado River basin for more than two decades. Even in years with close to normal levels of precipitation, less runoff is reaching the river — the result of increasing temperatures and drier soils drinking up the flows as climate change continues.
What happens if the Colorado River runs dry?
4. As the Colorado River provides less and less water, the 40 million people who depend on it must grow accustomed to living with less. Experts anticipate this will mean higher electric rates, more expensive groceries, cuts to the agricultural industry and less tourism, among other things.
