Flood tracking chart for 06191000 Gardner River near Mammoth YNP

To use the above flood tracking chart for a particular property near the Gardner River near Mammoth YNP gaging station:

  1. Determine the approximate elevation above sea level of the property.
  2. Convert the current stage to sea level using a sea level conversion factor of 5623.97 feet for this particular gage:
        2.11 + 5623.97 = 5626.08 feet.
  3. Compare the sea level in 2 to the elevation of the property to immediately know if the property has an impending threat of flooding.

Because the surface of flowing water is not flat and has a slope, the water-surface elevation near a threatened property might not be the same as the river stage at the gaging station.
