The high demand for water, the recent multiyear drought (1999–2007), and projections of global warming have raised questions about the long‐term sustainability of water supply in the southwestern United States. In this study, the potential effects of specific levels of atmospheric warming on water‐year streamflow in the Colorado River basin are evaluated using a water‐balance model, and the results are analyzed within the context of a multi‐century tree‐ring reconstruction (1490–1998) of… 

Predicting regime shifts in flow of the Colorado River

The effects of continued global warming on water resources are a concern for water managers and stake holders. In the western United States, where the combined climatic demand and consumptive use of

How Will Baseflow Respond to Climate Change in the Upper Colorado River Basin?

Baseflow is critical to sustaining streamflow in the Upper Colorado River Basin. Therefore, effective water resources management requires estimates of baseflow response to climatic changes. This

The twenty‐first century Colorado River hot drought and implications for the future

Between 2000 and 2014, annual Colorado River flows averaged 19% below the 1906–1999 average, the worst 15‐year drought on record. At least one‐sixth to one‐half (average at one‐third) of this loss is

An Assessment of Potential Severe Droughts in the Colorado River Basin

Much has been learned about Colorado River hydrology since the severe sustained drought study in 1995. We summarize our updated understanding of plausible future drought conditions by considering

Colorado River water supply is predictable on multi-year timescales owing to long-term ocean memory

Skillful multi-year climate forecasts provide crucial information for decision-makers and resource managers to mitigate water scarcity, yet such forecasts remain challenging due to unpredictable

Water availability to meet consumptive use demands over the next century in the Lower Basin of the Colorado River in the southwestern United States is considered under alternative climate and policy

Colorado River flow dwindles as warming-driven loss of reflective snow energizes evaporation

A Monte Carlo simulation with a radiation-aware hydrologic model resolves the longstanding, wide disparity in sensitivity estimates and reveals the controlling physical processes behind increased evapotranspiration in the Colorado River.

On the Causes of Declining Colorado River Streamflows

The Colorado River is the primary surface water resource in the rapidly growing U.S. Southwest. Over the period 1916–2014, the Upper Colorado River Basin naturalized streamflow declined by 16.5%,



Updated streamflow reconstructions for the Upper Colorado River Basin

Updated proxy reconstructions of water year (October–September) streamflow for four key gauges in the Upper Colorado River Basin were generated using an expanded tree ring network and longer

The Effects of Climate Change on the Hydrology and Water Resources of the Colorado River Basin

The potential effects of climate change on the hydrology and water resources of the Colorado River basin are assessed by comparing simulated hydrologic and water resources scenarios derived from

Multidecadal streamflow regimes in the interior western United States: Implications for the vulnerability of water resources

In the interior western United States, increased demand for water coupled with the uncertain nature of anthropogenic and natural hydroclimatic variations add challenges to the task of assessing the


ABSTRACT: The effects of potential climate change on mean annual runoff in the conterminous United States (U.S.) are examined using a simple water‐balance model and output from two atmospheric

A multimodel ensemble approach to assessment of climate change impacts on the hydrology and water resources of the Colorado River Basin

Abstract. Implications of 21st century climate change on the hydrology and water resources of the Colorado River Basin were assessed using a multimodel ensemble approach in which downscaled and bias
