A third of U.S. rivers have significantly changed color over the last 36 years, turning from blue to  yellow and green, striking new images reveal.

Researchers analyzed 235,000 satellite images — taken over a 34-year period between 1984 and 2018 — from NASA and the U.S. Geological Survey (USGS) Landsat program. The changing hues can be viewed in an interactive map.

More than half of those satellite images showed rivers with a dominant hue of yellow,  while more than a third of images were mostly green. Just 8% of river pics were mostly blue.
