I think beavers have been living in the Park for a long time. I remember seeing a beaver pond near Abrams Creek back in the early 90's. During the drought of 2007 and 2008 a big dam was built by them on Little River at the April Pool. We watched as it was under construction. Most people knew it was just a matter of time before it blew out. They live here in the valley along with the otters. I've seen both in the creek behind our house. Laurel Lake near our house is infested with beavers. They built a huge dam that blew out this year. I guess high gradient streams are not suitable habitat for those critters. But they live here, try to make a living and get by.
