WATCH LIVE: Tipping Point — The Colorado River Reimagined | A PBS News Special

The Colorado River is at a crossroads.

About 40 million people depend on the Colorado River for drinking water, and it irrigates more than 5 million acres of farmland. But a decadeslong drought along the river has depleted water levels in reservoirs Lake Mead and Lake Powell to record lows. Dwindling snowpack in the headwaters and ever-increasing demand from agriculture and municipalities have overtaxed it to a near breaking point.

"Tipping Point: A River Reimagined" begins at 7 p.m. ET Wednesday, Aug. 19. Watch live in the video player above.

After years of negotiations, the seven basin states — Wyoming, Utah, Colorado, New Mexico, Nevada, Arizona and California — could not reach consensus this summer on a long-term management plan to replace the expiring regulatory framework that has governed the river for the last two decades.

What happens now? Join PBS News science correspondent Miles O'Brien as he talks about the future of this critical waterway with scientists, policymakers and other stakeholders in a live event, "Tipping Point: A River Reimagined."

The U.S. Bureau for Reclamation, which manages the federal infrastructure on the river, has stepped in with a new proposal. Under the plan, Arizona, California and Nevada face mandatory water cuts in 2027 and 2028, with Arizona taking the biggest hit. Colorado and the other upper-basin states would face only voluntary targets, but are also reeling from record low river levels.

Guests for the livestreamed discussion about challenges facing the Colorado River and its future include:

  • JB Hamby, California's Colorado River commissioner
  • Becky Mitchell, Colorado's commissioner to the Upper Colorado River Commission
  • Tom Buschatzke, director of the Arizona Department of Water Resources
