I used to keep a grate on my overflow...I was mostly worried about the Grass Carp heading downstream, as is their nature around flowing water based on what I've read.

After the first time a major rain event occurred and I almost caused a spillway breach because the grate had clogged with debris I decided that losing a few (or even more than a few) fish during spring overflows was a much better option than losing the whole darn thing.

As such my culvert is wide open.

I have went down and looked at the pool of water below the spillway periodically after rain events...I've never seen anything larger than 2-3" fish in it up to now. That doesn't mean during high water I'm not losing larger fish that continue down the waterway but it still made me feel a bit better.

I've done some of my best bank fishing on the spillway overflows from larger lakes...it's a great spot to catch all sorts of fish, especially if it's somewhere not a lot of people know about/bother with.
