The U.S. Geological Survey recently released the results of modeling studies that project changes in water availability due to climate change at the local level. Scientists used several models to look at 14 basins across the country, including two in Wisconsin - Black Earth Creek and Trout Lake Basins.
According to the USGS, "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."
