Need help identifying

[taherrmann4]

I found this forum in searching for what type of snake this is, thought it was a brown water snake but I am not really sure, any help would be appreciated. It was living in and near my backyard pond and I think was feasting on some of my fish as the population has gone down some. I caught tonight and relocated to another pond that is away from people so he can have a good life. My dog actually found him tongiht.

Thanks in advance
