Record Low Snowpack Threatens Colorado River Runoff and Lake Powell
Record Low Snowpack Threatens Colorado River Runoff and Lake Powell
US · Published Mar 20, 2026
Record low snowpack in the Upper Colorado River Basin threatens water runoff and Lake Powell levels.
Warmer winter temperatures are causing early snowmelt, impacting the timing and efficiency of water runoff.
The Bureau of Reclamation forecasts Lake Powell's runoff at only 36% of average, raising concerns about water supply and hydropower production.
Snowpack at record lows in Upper Basin
The snowpack in the Upper Colorado River Basin has reached record lows, with snow-water equivalents at only 62% of normal levels. This alarming situation is particularly pronounced in Utah and Colorado, where snowpacks are at their lowest recorded levels, standing at 57% and 59% respectively. The crisis is compounded by warmer winter temperatures, leading to an early snowmelt, which disrupts the natural hydrological cycle. While snow typically begins to melt in mid-April, this year, the process started prematurely. Despite the early melt, the lower sun intensity results in a slow and prolonged runoff period.
