Study sheds light on what influences water supplied by snowmelt

Water often falls from the sky and is stored in mountains across the U.S. as snow before it melts and flows down to urban and rural communities. Knowing what factors influence when and how much of that snowmelt ultimately makes it to streams, rivers and reservoirs is crucial for water managers trying to make the most of limited water resources. A new study led by researchers at University of Nevada, Reno and the Desert Research Institute (DRI) published in Environmental Research Letters identifies three major factors that influence snowmelt-driven water supplies and identifies regions where mountain water supplies respond differently to climate change. The study used data from 537 watersheds across the U.S.
