Climate change projections indicate a steady increase in temperature progressing through the 21st century .....
.......generally resulting in snowpack reductions, changes to the timing of snowmelt, altered streamflows, and reductions in soil moisture, all of which could affect water management, agriculture, recreation, hazard mitigation, and ecosystems across the nation.
Despite some widespread similarities in climate change trends, climate change will affect specific water basins in the U.S. differently, based on the particular hydrologic and geologic conditions in that area.
New USGS modeling studies project changes in water availability due to climate change at the local level. So far, the USGS has applied these models to fourteen basins. See list;
