How Many Gallons Is My Pond

• To calculate gallons in pond
  
  Take your length x width x average depth x 7.5 = gallons
  
  If you have rocked in the sides and bottom of your pond, take out an additional 20% (.8).
  
  Example: 8 (L) x 6 (W) x 3 (D) x 7.5 = 1080 gallons
  
  For rocked in ponds: 1080 x .8 = 864 gallons
  
  If your pond is circular:
  Take your length x width x average depth x 5.9 = gallons
  
  On this calculation, your length and width should be the same.
  
  If you have rocked in the sides and bottom of your pond, take out an additional 20% (.8).
  
  Example: 5 x 5 x 3 x 5.9 = 442 gallons
  
  If you have rocks in the pond take your gallons and multiply them by .8 for more accurate gallons in your pond.  
  
  442 x .8 = 353 gallons
