+1 on the bamboo. I was thinking about Poplars behind the dam, but wasn't sure if they grew that far north. I was curious what others would think would work.
I would really be cautious about bamboo unless you have experience in control methods or you will be fighting it forever.
That stuff is bad IMO!
My neighbor planted some along our creek several years ago and it has spread into adjacent backyards - it will spread fast and get out of control.
There may other non invasive species......
