EXPLANATION OF LAKE SURFACE CALCULATIONS FOR EACH
COLUMN ABOVE^{
1}AC FT is a short term for Acre Feet which is one square acre at a depth of one foot
^{2}Square Feet = 43,560 Square feet per 1 AC FT
Therefore 772.2 AC*43,560 Sq Ft = 33,637,032 Sq Ft
^{3}Square Yards = Square Feet/9
Therefore 33,637,032 Sq Ft / 9 Sq Ft =
3,737,448 Square Yards
EXPLANATION OF LAKE VOLUME CALCULATIONS FOR EACH COLUMN
ABOVE
^{4}Acre Feet in volume terms takes into consideration
average depth
Therefore 733.3 AC FT * 6.9 Ft avg depth =
5,043 AC FT of volume
^{5}Cubic Feet = 43,560 per AC FT
Therefore 5,152 AC FT * 43,560 Sq Ft per
AC FT = 224,464,680 Cubic Ft
^{6}Cubic Yards = Cubic Feet/27
Therefore 224,464,680 Cubic Ft/27 =
8,313,506.4 Cubic Yards
^{7}Million Gallons = cubic yards * 201.974 gallons per cubic yard
Therefore 8,313,506.4 cubic yards * 201.974
gallons = 1,679,100,000 gallons
