I’m looking for feedback /concerns on my idea for pond construction. (see attached pictures) I will be having some test holes dug this week. My main concern has always been how to handle the large amount of flow during large down pours (drainage area is 250 acres). My idea is to have a smaller sediment pond with a smaller pipe( 8” to 10 ”) that feeds the main pond. This pipe would be sized to handle the normal creek flow. The sediment pond would have a spill way that leads into a diversion channel that goes around the main pond. The diversion channel would be about 30’-40’wide 3’ and 3 to 4’ deep and planted with grass. The main pond would have a normal stand pipe but larger guessing 18” or so. Thanks for your thoughts!
