This is a short clip of my first swale and berm system in action. Please excuse the mess, I wasn't planning on taking a video, but I had to jump at this opportunity. I had just built it and hadn't even planted it yet. The video was taken during a heavy rainfall and it didn't overflow any of the berms, which let me know that my design was effective.
Since then, I have moved, but when I drive by, it looks like it is still functioning.
