1 cubic yard = 201.974 gallons
1 gallon = .004951 cubic yards

These are estimates based upon the 1999 data. Actual amounts will vary through seasons and different weather patterns

A Source: The data in these columns and cells are from a document prepared for the Nobles County Soil & Conservation District by Houston Engineering of Fargo, ND on 3-15-1999 based upon measurements taken in the 1999 Lake Bottom Study

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
2Square Feet = 43,560 Square feet per 1 AC FT
     Therefore 772.2 AC*43,560 Sq Ft = 33,637,032 Sq Ft
3Square Yards = Square Feet/27
    Therefore 33,637,032 Sq Ft / 27 Sq Ft = 1,245,816 Square Yards

EXPLANATION OF LAKE VOLUME CALCULATIONS FOR EACH COLUMN ABOVE
4Acre 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
5Cubic Feet = 43,560 per AC FT
     Therefore 5,152 AC FT * 43,560 Sq Ft per AC FT = 224,464,680 Cubic Ft
6Cubic Yards = Cubic Feet/27
     Therefore 224,464,680 Cubic Ft/27 = 8,313,506.4 Cubic Yards
7Million Gallons = cubic yards * 201.974 gallons per cubic yard
      Therefore 8,313,506.4 cubic yards * 201.974 gallons = 1,679,100,000 gallons
