If you have some trophy fishes would putting a net near the overflow make sense so you dont lose em?
Probably not a good idea. Mesh small enough to capture small fish would catch a lot of trash too. My grass carp fence on the emergency spillway is made with rebar on 2" centers, and it flows well but it does allow smaller fish to escape.
We went from a forecast of almost 3" to nada. Laura's moving slowly, so that could dump lot's of coastal rain.
