The 12 inch spillway pipe kicked into full siphon mode about 6PM today. I've never seen one flow before! I had planned for it, hoped it would work, but dang it's really something to see that rascal pump. The water was landing about 15 feet from the end of the pipe. With all the rain we've had, I still expect the emergency spillway to overflow tonight. I have 530 acres of watershed, so my problem is more getting rid of water than catching water. The emergency spillway is 40' wide with 4' of freeboard above the bottom of the spillway. I think that iw needed with this much watershed, even with a 12" siphon.
Here is two pictures of just before it went into siphon, and one in full siphon.
