I am in the process of building something along that line. My forage/sediment pond will be slightly up hill from the main. That is the direction the watershed water enters. I am building a riprap filled ditch between the forage and main at a depth that the ponds will share water at normal pool or above thru the ditch. The berm is around the main.
