Sounds like you've got it figured out, but here is what I did on my smaller ponds, especially my previous trout pond where water was constantly overflowing out. I would think you could do it on larger ponds on a bigger scale.

In the trout pond I had a problem with floating algae clogging up the screen, and of course leaves in the fall. I built a floating boom that was made of PVC in a 'U' shape that floated in front of the outlet. The closed end of course faces out. Any floating debris gets backed up against the PVC, but would still allow the water to still get through.

I wish I had a picture but haven't used it lately as the three smaller ponds are no longer flow through ponds. My biggest pond has an emergency overflow only as I don't trust putting pipes through dikes.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
