Well be just got an inch of rain and the pond siphon is working but I also have water going down the emergency spillway. I'm thinking by the time the water is over the 10" pipe to start siphoning I am already at emergency spillway elevation or close to it. I just dont have the added capacity to allow time for the siphon to keep up. I think the answer is to add 2 or three feet to the dam brest.
