Hi Matt,
Welcome to the forum! Glad you found it early in your pond's life, I didn't, and wish I had. Loads of great info and wonderful folks here. I'm up in the Appleton area, and you'd be welcome to swing by and see what I did for water control. I had some previous posts with diagrams. Looking forward to hearing more about your project.

Jeff

I used to think I was crazy and all alone...
Now I know I am not alone!
