The Colorado River provides water to 40 million people in seven westernstates and two countries and to 5.5 million irrigated acres. The river haslong been overallocated. Climate models project runoff losses of 5–20%from the basin by mid-21st century due to human-induced climate change.Recent work has shown that decreased snow albedo from anthropogenic dustloading to the CO mountains shortens the duration of snow cover by severalweeks relative to conditions prior to western expansion of the US in the mid-1800s,and advances peak runoff at Lees Ferry, Arizona, by an average of 3 weeks.Increases in evapotranspiration from earlier exposure of soils andgermination of plants have been estimated to decrease annual runoff by morethan 1.0 billion cubic meters, or ~5% of the annualaverage. This prior work was based on observed dust loadings during2005–2008; however, 2009 and 2010 saw unprecedented levels of dust loadingon snowpacks in the Upper Colorado River Basin (UCRB), being on the order of5 times the 2005–2008 loading. Building on our prior work, we developed anew snow albedo decay parameterization based on observations in 2009/10 tomimic the radiative forcing of extreme dust deposition. We convolve low,moderate, and extreme dust/snow albedos with both historic climate forcingand two future climate scenarios via a delta method perturbation of historicrecords. Compared to moderate dust, extreme dust absorbs 2× to 4× the solarradiation, and shifts peak snowmelt an additional 3 weeks earlier to a totalof 6 weeks earlier than pre-disturbance. The extreme dust scenario reducesannual flow volume an additional 1% (6% compared to pre-disturbance),a smaller difference than from low to moderate dust scenarios due to melt season shiftinginto a season of lower evaporative demand. The sensitivity of flow timing todust radiative forcing of snow albedo is maintained under future climatescenarios, but the sensitivity of flow volume reductions decreases withincreased climate forcing. These results have implications for watermanagement and suggest that dust abatement efforts could be an importantcomponent of any climate adaptation strategies in the UCRB
