As some of you know I have 2 small ponds in close proximity, ~50ft.

I want to connect the two for drainage purposes, but not allow fish to travel between them, as I want a different species set in each pond. I wanted something better looking than a culvert pipe with screen on the end. I came up with this design:

French Drain Culvert

I guess my main question is, do you think fish eggs will still get through this? More so than ducks transferring them between the ponds?

I have a bunch of heavy driveway fabfric that I will use to install the surge rock, I could even put this over the ends of the culvert too, but not sure if over time it would get clogged up.
