Naw, I've been to crane estate before and it wasn't it. Ipswich and Essex rivers are also both places I like to go to. Thank you

Awesome! Thank you. I'll dig around tonight and on my lunch break later

Naw, this is still good though, I'd love to check this out later on. It was a stream, pretty narrow, it went from a normal stream to an irrigation ditch about 3-4 feet wide. I didn't use a tube, just kind of swam and floated along the stream all day and walked like 6 miles through the woods back to my car. We didn't do that for the trip, we just kind of toured the site. It was when I came back that I decided to swim along it for the hell of it, I don't think it's something folks typically do as a tourist site. It was me just kind of doing my own thing, but I remember there was a pretty strong but not too fast current, it went from a rocky steam bed near the historical site to like a soft clay when it became an irrigation ditch. I'm betting there are probably a number of places similar to this all over mass, so my hope in finding this place again is kinda slim. Thank you!

UMass Lowell. I'm pretty sure this was something I first visited in school, but there's a possibility it could have been in boy scouts
