Here is some random trivia...I was double checking math on aquatic herbicides and needed to know the volume of water that our lake holds. The lake is 380,352 square feet or 8.73 acres.
Lets say the average depth over the whole lake is 4 feet...
1,521,408 cubic feet.
1 cubic foot = 7.48 gallons of water
The lake holds roughly 11,380,922 gallons of water.
