Since the mid-21st century, runoff in the Colorado River Basin has been about 13 to 15% less than in the mid to late 20th century, Schmidt said. Year over year, the basin has experienced reduced supply, often combined with a string of very dry years, and the river system has never been able to adequately rebuild its supply.

\"During those very dry years, we deplete reservoir storage because society is not able to reduce its use at the same rate that nature reduces its supply,\" Schmidt said.

The lower basin states have submitted an allocation plan for consideration, but there is not yet a consensus plan among all of the states, including the upper basin states, Dave White, director of the Global Institute of Sustainability and Innovation at Arizona State University, told ABC News.

If the states can't reach a negotiated agreement, the Bureau of Reclamation will need to intervene to make a final decision, Schmidt said.

\"The Department and Reclamation remain committed to reducing the collective risk of both Lake Powell and Lake Mead falling below critical elevations to protect critical infrastructure so that it can continue to function as authorized to meet the water and hydropower needs of the basin,\" Soeth said.

The Bureau of Reclamation is set to release another update to the projections this week.
