Scientists say water levels at Lake Mead and Lake Powell are dropping to dangerous levels, reflecting the Colorado River's worsening "structural deficit."

The Colorado River that runs through Grand Canyon National Park supplies water to nearly forty million people in the West. But longstanding programs to protect the river’s health are about to be defunded by the federal government. River managers say the result could be disastrous for the crown jewel of the national parks. KNAU’s Melissa Sevigny reports.

The U.S. Bureau of Reclamation projects a 52 percent chance of a water shortage on the Colorado River in 2020. Arizona would bear the brunt of mandatory cutbacks. KNAU’s Melissa Sevigny reports.

Mexico and the U.S. states of Arizona and Nevada face a better-than-even possibility of getting less water from the Colorado River in 2020 because of a persistent drought, water managers said Wednesday.

A dry winter for the region feeding the Colorado River means Lake Mead's water level could drop, but not enough to trigger an emergency shortage declaration that would force water cutbacks in Nevada and Arizona.
