So the stream never leaves yer land? The way I read it is if the overflow leaves yer land you need a license.
Interesting Point Bill, yes the water does leave my land. I will have to find the actual law and do some more research. The egress part of this statement is very vague.
Now maybe one could argue that if water is not running out the spillway then the water is not egressing and you are legal

Thanks for catching that.
