I have a small impoundment that we flood each year. In years past We have simply filled in the end of the drainage ditch to flood and dug it out in the spring to drain. I want to control the water better ( and I am tired of hand digging it) and I was thinking of putting in a pvc pipe with an elbow to control water level a littl better. I want to be able to rotate it to let the water go up or down as needed. Is there anything I need to put around the pipe itslef that is buried in the dirt so the water wont run down it and ultimately create a leak? Is this an effective way to control water? I have heard of this before I just dont want it to leak half way through the season when we need water for birds. Any sugvgestions on how to do this right would be great. Its only about 2 acres Thanks Glad to finally get on this site. The info in the habitat forum is always interesting for me. Waterfowl habitat creation and management is a big reason I love this sport so much. Hoepfully I can contribute to some questions other people have.
