Colorado’s snowpack levels in 2025 are raising concerns among water managers and climate experts as the state grapples with drought and the impacts of climate change. While some regions are seeing near-normal snowpack levels, others are experiencing alarmingly low snowpack, which could affect water supplies once runoff begins in the spring.

Regional Variations in Snowpack Levels

The state’s snowpack levels vary significantly across different regions. Northern and central Colorado are experiencing near-normal snowpack levels, while southern Colorado is struggling with significantly below-average snowpack. The San Miguel-Dolores-Animas-San Juan basin, for example, is currently at only 61% of its median snowpack level. The Upper Rio Grande Basin is also facing challenges, with snowpack levels at 64% of the median.

Impact of Drought and Climate Change

The drought conditions in Colorado have been exacerbated by a dry January and near-record high temperatures throughout the winter. The state’s overall snowpack is at 82% of the median between 1991 and 2020, reflecting the impact of prolonged dry conditions. Climate experts warn that even with a promising start to the snow season, long-term drought concerns persist, particularly in the Colorado River Basin.

Water Supply and Runoff Forecasts

The variation in snowpack levels means that water supplies could vary greatly across the state once runoff begins in the spring. Reservoir storage remains relatively unchanged, but streamflow forecasts have decreased since January, now at 89% of the median. This decrease reflects the persistent dry conditions and the impact of January’s below-normal precipitation.

Looking Ahead

As Colorado continues to monitor snowpack levels and water supplies, the state’s water managers and climate experts remain cautiously optimistic. Late-season storms could still have a significant impact on snowpack levels and runoff, but the long-term challenges posed by climate change and drought require ongoing attention and adaptation.
