Locations of stream systems that may soon experience significantly low flows. Color bubbles indicate location of the stations and loss-of-flow estimates in cubic feet per second (cfs) per day per year. The size of the bubble is proportional to the magnitude of trend value. The image was generated using data from the U.S. Geological Survey’s Hydro-Climatic Data Network. Credit: Maryam Pournasiri Poshtiri and Indrani Pal
