Q&A: Wading into the shrinking waters of the Colorado River

Key agreements in the “Law of the River,” which encompasses more than 100 years of regulations, laws, court decisions and more focused on managing the Colorado River, are set to expire next year. First established in 1922 as the Colorado River Compact, the guidelines split water management and allocation among seven states. Now, those states — Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming — are renegotiating the terms of use for the water. Drought, increased temperatures and decreased snowpack in the Rocky Mountains are complicating the matter, according to Antonia Hadjimichael, assistant professor of geosciences at Penn State.
