I'm thinking I dont really need one. I had maybe 3 that I found (escapees). They were little tiny. I dont have a huge watershed incoming to the pond. Maybe 2 acres at most. With the pond now sitting around ¾ acre it prolly wont over flow as bad. Time will tell on this.
Wow theres noway I have that much water flow for 2 -24 pipes. I have seen a few spillways that I like. I believe its T-bar has a nice looking one.
