WILL YOUR CITY RUN America's Water Risk. Columbia University researchers have developed a metric called the Normalized Deficit Index (NDC) to reveal areas facing the greatest risk for multi-year droughts. DRY?

Here are the findings. 60 Years of Daily Precipitation Demand Usage Patterns AREAS AT RISK Variations of Supply This map illustrates the areas facing the highest potential shortage, using only local water resources to maot their current water use. It draws from 60 years of data on water supplies and use. Red a the highest risk; dark green is lowest.
