Record low levels at Lake Powell threatens water and electricity supply

Key Points:

• Lake Powell, the U.S.'s second-largest reservoir, has reached a record low water level of 3,519.91 feet, slightly below the previous low set in April 2023, signaling worsening conditions in the Colorado River system.
• This milestone follows Lake Mead hitting historic lows about a week earlier, with both reservoirs now at their lowest combined storage since 1957, threatening water supply, wildlife, and hydropower for over 40 million people across seven states.
• The ongoing drought, overuse, and rising temperatures have contributed to the decline, complicating efforts by federal and state officials to agree on a long-term management plan for the Colorado River Basin.
• Lake Powell is nearing the critical point where hydroelectric turbines may stop functioning, with federal officials warning that major interventions will be required to prevent power loss by the end of the year.
• The water shortage is also impacting local economies, forcing changes in Lake Powell’s tourism infrastructure, including marina relocations and boat ramp adjustments to adapt to lower water levels.
