Im not sure I understand the erosion part, but thinking you mean the water is backing up and then taking a different "exit"? This alternate exit is eroding. Just my opinion, and I am no expert, but yes I believe it is illegal to back water up on a neighboring field like that because they are stopping the natural flow of water. I have built a couple dams similar to that, but 120' on my side of the line. In a huge rain event it will back water on to them temporarily. However it has yet to cause crop damage and the neighbor agreed it was ok to do it because it also benefits them. Erosion eats its way back to the source of water, so my side eroding eventually would have led to their side eroding.
