The southwestern United States is having its worst megadrought in 1,200 years. New research suggests that this drought could persist for decades, as ongoing warming disrupts the region’s vital rain cycles. Models suggest continued global temperature rises could keep the Southwest in a dry regime through at least 2100.   The Pacific Decadal Oscillation (PDO)…

The Bureau of Reclamation (Reclamation) is beginning an environmental impact statement (EIS) for the Verde River Sediment Mitigation Project in northern Arizona. This comprehensive study will examine options for restoring lost storage capacity due to sedimentation.    The goals of this EIS include restoring the lost capacity of Horseshoe Reservoir and mitigating future sedimentation throughout…

The annual Tahoe: State of the Lake Report (Report)provides updates on the ecological health of the lake, discussing past and ongoing environmental challenges. UC Davis has conducted continuous monitoring of the lake since 1968. This accumulated data provides invaluable insights for this iconic, but vulnerable lake.   The latest 2024 Report indicates that Lake Tahoe…

Utah’s agricultural program to reduce water use through improved efficiency is showing some encouraging results. Nearly 700 projects have secured funding under the Utah Department of Agriculture and Food’s Agricultural Water Optimization Program. To date, 250 projects have been completed resulting in annual savings of over 40,891 acre-feet of water! This volume of water could…

Severe weather events, particularly heavy rainfall, are becoming increasingly common. Having reliable assessments of location and timing for such occurrences is crucial for saving lives and property. Researchers have developed a new AI method that converts low-resolution global weather data into high-resolution precipitation maps.    Researchers utilize historical weather model data, which describe global precipitation…

The Kootenai River originates from glaciers in Canada and its watershed spans over 19,000 square miles across British Columbia, Montana, and Idaho. The river crosses the US-Canada border twice. Residents on both sides of the border share its waters and its pollution.   Researchers have recently launched a $4.9 million transboundary study aimed at promoting…

Aging dams and other river barrier infrastructure pose an increasing risk to communities. New research explains that dam removal can significantly enhance safety and resilience against extreme weather.    The research paper, “Barrier Removal is a Strategy for Climate Resilience,” from Utah State University highlights how removing outdated or unsafe dams and barriers can improve…

Droughts are having increasingly significant economic impacts. A new report shows that without effective adaptation, the costs associated with climatic events could surge by at least 35% by 2035.    The global land area affected by drought has doubled since 1900. In recent decades, nearly 40% of the planet experienced increased frequency and intensity of…

Wildfires devastate forests and watersheds leaving behind contaminants that continue to pollute rivers and streams longer than previously estimated. A new study offers the first large-scale assessment of post-wildfire water quality. It analyzed water quality in over 500 watersheds, aiming to identify trends in post-wildfire water quality across the entire US West.    Fire ash…

Storms coming from atmospheric rivers bring vital moisture to the US West Coast. However, they also cause most of the region’s floods. Storm size alone does not always predict flood risk, ground conditions also play a critical role.    New research explores the drivers of floods, by analyzing decades of atmospheric river storms. It examined…
