A new Bureau of Reclamation report concludes that projected temperature increases as a result of climate change are likely to affect the timing and quantity of stream flows in all western U.S. basins. In turn, that possibility could have a significant effect on water supplies in that region, says the congressionally mandated study, released on April 25.
