Not disagreeing with anyone but I have a massive weeping willow next to one of my 1/10th acre ponds. And even with it not getting well water for trout, I don't notice an appreciable drop in water level. But I do see the roots in the water!
The the thing I do hate about the willows I have on the property is their messiness: they drop lots of branches! And if you have a connection in a drainpipe thst is not water tight they will work their roots in and clog the pipe. Been there done that!
