Not the one across the front of my place .
I have a 15'' culvert and the ditch going into and out of it is 3or 4 feet wide and deep.
Either the ditch must be to big or the culvert is to small.
But which one?[/quote]
Take your choice... the answer is both the same.

Late me put it another way :
You need to drain water, If you decide to do it using a Culvert what size culvert do you need ?
If you decide to forget the culvert and go with just a ditch what size for the ditch?
The answer to the two part question you posed above is:
A) Why do you need to drain water?
B) Large enough to carry all the water that will be going through the culvert.
C) Why would you forget the culvert?
D) Large enough to carry all the water that the ditch will accumulating.
