Was someone else cleaning up the Nashua River?

Saturday I went paddling on the Nashua at Center Rd. When I got there I saw 2 bags of kitchen trash on the path in the corn field I park in. The Nashua River Watershed Association booklet says it's private property, and apparently the owner doesn't mind kayakers parking there. So I cleaned up that trash and went to work.
Upstream there are some logjams that typically catch a lot of trash, but they were almost empty. Did someone clean up? If so, thank you!
So I collected some other stuff and went back downstream. At the big logjam I've been working on, I tried to collect some stuff out in the middle. See the before and after



Again, it's not ddone, but I've getting close.
