I cant watch the video.... dumb filters, either way when you designed your swale what amount of rain did you use to figure your catchment? Did you plan in over flow points?

I am designing 2 swales for the farmstead and that seems to be the current issue, how large should the swales be and where and how large of the overflow...

I used 1.5 inches per hour. That rarely happens. Rivers all over the county broke records so this event was extremely unusual. Even when Bill moved through here we got 6 inches of rain over a 24 hour period and the swale handled it fine. What I believe happened was the road to the south had all it's ditches clog with leaves and overflow that made all that water come to us. I had not anticipated that in my design. There is roughly 40 acres sloping toward the ditch on the road and I have no idea how I would even calculate how much of that gets to this property.
