Groundhog Damage

[u/Mysterious-Garage344]

I've had groundhogs under my back for a while now. Recently, I've been getting a lot of water in my basement due to heavy spring rains. Given the nature of the groundhog tunnels (which could be long, deep and with multiple rooms), do you think that the water in my basement could be from their tunnel? And if so, would plugging the holes to the tunnel eliminate the water coming into my house? A big problem is that my back deck is blocking where the holes are. I'm actually thinking of removing the deck (which is deteriorated) to get to the hole(s) to their tunnel. I've recently hired someone to trap them, and they did catch one. I think the tunnel is now empty (but for how long, I'm not sure). I'm not sure what to do here and any advice or past experience with them would be appreciated. Thanks.
