Welcome to the forum
I have a six acre pond that has two 24” culverts side by side and no cover over either one they haven’t stopped up in the 10 yrs that they have been there, have had a few branches that got in front of opening nothing to impede the flow.
Only once in ten years has the water ever gotten to about 2” deep in culverts not enough to suck anything other than sticks and leaves
