Here’s why 3 decent winters in a row still isn’t enough to fill Lake Powell: This week is when snowpack typically peaks across the #ColoradoRiver Basin — The Salt Lake Tribune

Over the last three years, the Colorado River Basin has experienced three relatively healthy winters. But that decent snowpack, after melting, hasn’t filled reservoirs like Lake Mead and Lake Powell as much as water users across the West might like, due to years of drought and overuse. Recent forecasts show Lake Mead and Lake Powell will remain roughly one-third full after snow melts down from the mountains across the West into the Colorado River and its tributaries this year…

Winter of 2023 brought substantial snow to the parched region, with snowpack levels reaching over 150% of the 30-year median. The banner snowpack led to 10.6 million acre-feet of water flowing into Lake Powell over the spring and summer — a whopping 166% of the average runoff seen between 1991 and 2020. That helped bring Lake Powell up to 38% in July 2023 after the reservoir hit a record low of 22% in February of that year. That was followed by another good snow year for the basin basin, with levels hitting 113% of the median in 2024. But that above-average snowpack translated to a below-average runoff of 83%, or about 5.3 million acre-feet of water reaching Lake Powell. That was lower than what forecasters had predicted earlier in 2024, and the reservoir saw a smaller bump — reaching 42% full in July.

The discrepancy between snowpack and runoff was largely because soil across the Colorado River Basin was so dry, [Jack] Schmidt said. Dry soil absorbs melting snow, so less water ends up in reservoirs. And this year, soil across most of the Colorado River Basin is drier than normal — and even drier than it was this time last year.
