The origin 😊
It’s amazing that the water source is in the basement of a house 😮

Headwaters 🤩 I love the name 🤩 It sounds like it was brewed for fly anglers 😉 Crisp, citrusy, and dry. It feels like a session IPA but with nice strength and depth 😊😋 And local too 😉

I love finding headwaters 😉
But this one might not be so clean - some of the water seems to be coming from the pipe on the left, likely connected to the road above 🤔
It’s icy, I’ll come back in the spring to see if this pool holds any fish 😊
