Put a drain pipe in the dam and let it stick out about 6 feet. The beavers will try to fix the leak but can't because of the pipe. If you drain plant Japanese millet. It takes about 90 days to mature. So plant according to the season. Yes, the beavers will re-flood the pond for you. Learn to work with them. It will save you time. Live in harmony with nature. Less stress.

thanks for the help i have read somewhere that instead of planting i could just drain the beaver pond in June for several weeks and let the sun help grow natural vegetation. Then flood the lake again. This sounds better for my type of land and money. My new question is where can i see plans for how to drain the top part of the pond without destroying the dam and then one to control the water level after it is flooded again
