Dams normaly have a specificly designed spillway as it could otherwise be VERY dangerus (the water removeing dirt at its base , possably leading to dam failure)
I doubt the solar panels were put on it tho
If water is just overflowing it entirely like a glass of water then shits so fucked that the solar panels just dont matter
Ive seen some places introduce multiple sizes of shoping carts
Large, same design but what? 20% smaller? and kid sized but with a pole and a grip
