Flood tracking chart for 06036650 Jefferson River near Three Forks MT

To use the above flood tracking chart for a particular property near the Jefferson River near Three Forks MT 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 4076.76 feet for this particular gage:
        2.71 + 4076.76 = 4079.47 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.

The National Weather Service is responsible for forecasting flooding and setting flood stages, which are subject to change. The graph on the right is from the National Weather Service Advanced Hydrologic Prediction Service. Visit their web site for additional forecasts and more flood stage information.
