I have seen many of his other videos showing what he does for a living and thats cleaning out culvert pipes that have been blocked off by beavers and it seems the busy beavers keeps him busy.
Living inside a colvert pipe like that is at risk of being flooded, the video shows him doing this durning winter and there is snow on the ground and all it would take if for the weather to warm up some and have it rain really hard and he would have to abandon his camp because the water level is about to come up 10 to 15 inches and maybe more.
