Pond needs

What do I need to know before making a pond?

I have a 15 gallon tank with 5 fish and they are all really small.  I know for a fact they are going to get really big so I was thinking about making a pound in out yard in a spot where there are no power or water lines and keeping the big fish out there and raising the smaller ones inside until they get big enough to go in the pond.  Keep in mind i'm only gonna make it 10ft long 7ft wide and the deepest part about 9ft.

Do you have any tips on a pond?

Answer:

First of all, you don't need a pond 9' deep. Depending on where you live, 18" to 3 feet is usually deep enough. Your frost line (You can find out how deep your frost line is by calling your county extension service), determines how deep your pond needs to be. You will want to dig deeper than yours is.
