Thanks Guys. Brian, I think I have a roll of that stuff in my shop somewhere. With possibly another storm headed our way...I am going to put something in place!! Just never really thought I would need it. Live and learn.
I've had my emergency spillway in use just once so far. Never had 22 inches in a few days, but then I'm considerably farther from the Gulf than you are.
A word of caution: Since you do need the spillway for hurricane type events, perhaps it is better to lose some fish than potentially block up the emergency spillway. If debris gets caught in it, the water will still overflow, only at a higher level & intensity. You might even lose the whole dam.
Maybe I'm being paranoid, but it is something to consider.
