   Acquired on April 6 and March 27, 2023, by the Moderate Resolution
   Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite, these two
   false-color images show rapid changes in water level on the Gascoyne
   and Murchison Rivers in Western Australia. Simply clicking on the date
   below the image reveals that both the Gascoyne (north) and the
   Murchison (south) Rivers were nearly completely dry on March 27. Only
   10 days later, on April 6, the rivers were not only visible, but
   appeared to be flooded.

   The Gascoyne and Murchison Rivers are both ephemeral waterways, which
   contain water only part of the year. They tend to hold water near the
   end of the rainy season (April) or after heavy rains drench central
   West Australia, where the rivers or located or their extended basins.
   Rainstorms have impacted north and central Western Australia recently,
   especially in late March through early April.

   This type of false-color image helps separate water (blue) from open
   land (tan, brown, or pink tints) and vegetation (green). In the earlier
   image (March 27), it is easier to see the course of water in ephemeral
   rivers by the streaks of green that mark vegetation growing wherever
   water exists rather than blue of the water. This is because water
   volume is extremely scant, but enough to support growth of tenacious
   plants.
