we have a wooded area behind the house that used to be a pond around 30 years ago. the dam is still there but the creek broke through it and left around a 20ft gap. my question is what is the best method to dam the creek back up? put a 90 degree pipe in and fill in with red clay? located in GA
we only need it to be a foot or two deep to hold ducks and practice dog training

Consider using a flashboard system if wanting a flooded waterfowl area. You could pour some concrete and use 8-12' long boards to adjust levels as needed. Put a bead of silicone on boards to improve sealing.

Does the creek run continuously? Or is it seasonally dry?
The reason I ask is, if it runs continuous you could just stack rocks or rip-rap through the cut up to the desired level of water. The water would rise and fall along with the creek flow, but back up into the pond area at least part of the time.
When I was a kid (with too much time on our hands in the summer), we would play in the creek and take boulders in a riffle area and stack them up. It would back up a nice pool of deeper water.
Where you only want a limited amount of water in the pond area, anything to restrict flow of the creek water might do what you need.
That is if the creek flows pretty much year round instead of seasonal.

it flows year around, there are two other lakes upstream from us, I am looking to use a 6inch pipe and cover it with clay. this will be a .25 acre 2ft deep wood duck hole, what is the cheapest method for a drainage pipe?

Could ya cut a tree about 10" and put it in place and then pack clay?

It may sound like a lot of work, but if you don't calculate how much watershed you have, and use that number to figure out how many gallons of water the creek will see from a significant rainstorm, your dam and pipe might get washed downstream again if the pipe isn't large enough.
Just saying.............
I've used black corrugated double wall "culvert", and put a 90° elbow on it, then extended the vertical pipe to the height that I needed, cutting it with a recip saw.
I'm thinking that 6" is way too small.......................
You can do it cheap and it might hold, or you may have to re-spend the money because it failed. I usually opt to do it once, no matter what it costs because I don't want to have to do it again.

A=πr^2 (area = pi times radius squared) Do the math. What's cheaper, four 6" pipes or one 12" pipe? That's what you'd need to get the same cross section......... (unless I did the math wrong) You sure you're looking at double walled culvert? Go to a plumbing contractors supply house - you most likely will beat the big box store prices...... I come up with a 12" elbow for around $67.00. http://www.alantlynninc.com/Culvert.html

what about taking a metal pipe say 2-4ft in diameter and putting a sheet of metal over it like a water control valve. You could winch the sheet of metal up to let water out.
