I have a sediment pond upstream from my big pond. We use the 'dry dam' (why it's called a dry dam I have no idea, there's water on both sides) to cross the creek. We have the overflow lined with riprap. It's worked well for 5 years now. Really seems to hold the sediment well.

Added bonus for me, I use the sediment pond as a forage grow out...I put FHM's in it. They are going bonkers - and have no predators beyond frogs and birds. When the water overflows some wash into the big pond. And my plan is towards the end of the summer to see how many I can seine out. Hoping it'll be a perpetual source of food for the big pond.
