As long as he doesn't flood out the front lawn, which is improbable, he won't be a problem. DNR has a whole list of folks who can get rid of him. He probably won't stay real long as there aren't any other beavers around. Probably got washed down here from PA a month ago in that horrible rain storm we had. Everything flooded. My lawnscape guy can play a game of I'll tear out that dam as fast as you can put it back together, Mr. Beaver. Think of Caddyshack. The dam itself is easily accessible for a vehicle, one piece of rope and the truck and instant destruction. I saw a coyote here earlier this week. They eat beavers.
Good luck with all that. We had trouble with beavers at our sportsmens club maybe ten yrs ago. We have a trout nursery (raceway) next to the stream that we divert water thru it to raise trout. We initially thought we had one beaver, but we had two. By the way, They travel in pairs and mate for life. They built a dam upstream of the nursey and it began to divert the water around our nursery. Plus the dam raised the water temp. This was mid summer when temps can be crucial. Trout need cold, clean,moving water.
In the beginning we thought the beavers were pretty neat. We built a bench from a plank and two large billets of firewood. I spent almost an hour there every evening for the first two weeks, sitting on the bench, watching them work and taking hundreds of pics. It became a neighborhood attraction. They are amazing to watch work. Cutting trees and bushes, carrying them, and using their little hands to place them. Un like what you would think, beavers place their material parallel with the stream. Not perpendicular like a person would think.
Anyhow it wasn't long till we decided they were going to be a problem. For the next month several of us spent an hour every evening tearing out the dam. Only to find it repaired the next evening. And it seemed to get bigger and better each time. Dad built a grapple hook and we started using his jeep to drag it apart. This was becoming a losing battle. Plus the extra hour I had to invest everyday was growing old. We finally contacted the Pa Game Commission and they provided us with 2 suitcase traps. Over the next couple days we were able to trap them and transfer them to another area about 20 mile away. Ironically that area is known as the beaver dams.
We tried hard to co-exist but it didn't work out. We tried to defeat them, and that didn't work out. Move them was the only answer
But they were really fun to watch. They would be busy for hours while we watched from the bench. Almost aways within 10-12 feet from us. And coming to a few feet to get apples we gave them. Yes beavers eat apples. Sometimes they would slap their tail which is neat to see.
Anyhow Im done rambling. Good luck. You may be in for a battle.
