The Colorado River is an essential water source for more than 40 million people, 5.5 million acres of agriculture, 30 federally recognized tribes, and the vibrant wildlife along its course through the Southwest. But the river is under threat — the impacts of climate change and the continued drying out of our region have reduced water levels dramatically. The amount of water flowing in the river today is significantly less than the early 20th century when the Colorado River Compact of 1922, the original agreement between the seven basin states divvying up the river’s water, was put in place.

The initial Interim Guidelines were developed in 2007 in response to these changing conditions on the river. These guidelines helped coordinate how much water is kept in or released from Lake Powell and Lake Mead, mapped out how shortages will be implemented if reservoir levels and water supplies reach specified elevations, and facilitated state and federal cooperation to avoid shortages. They were an important first step in helping states and water resource managers adapt to the changing hydrology of the river, and work as a tool for planning against an increasingly unpredictable future.

As the name suggests, the 2007 guidelines are an interim agreement and set to expire in 2026, providing a rare and historic opportunity to protect and re-set the equilibrium of the Colorado River. States, tribes, communities, industries, and agriculture interests, among others, will be vying to protect their share of the river’s water in upcoming re-negotiations. WRA and our partners are working to ensure the Colorado River will remain healthy and flowing now and for future generations.

We can’t afford to miss this pivotal moment for Western states to start planning for a future with less water in the Colorado River.
