05101000 TONGUE RIVER AT AKRA, ND

PROVISIONAL DATA SUBJECT TO REVISION

Prior to December 1973, gage at different location and datums.

To use the above flood tracking chart for a particular property near the TONGUE RIVER AT AKRA, ND 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 930.0 feet for this particular gage:
       7.31 + 930.0 = 937.31 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.
