Clubtail? - Gomphus borealis

Yes, definitely Gomphidae

but they are notoriously difficult to ID. Certainly looks very similar to the Dusky clubtail, Gomphus spicatus, with those darkened colors and narrow abdomen. Luckily we have a couple of excellent northeastern Odonata experts on BugGuide who should be able to sort this out for us.

I agree with Tom re sp.

The wide flare of the terminal appendages suggest Beaverpond. Most unlikely to be Harpoon G. descriptus as this is a species of lotic habitas.
Compare against these spp.

Gomphus borealis

To me it looks like a Beaverpond Clubtail. The club is develpoed just a little too much for Dusky. The shadow of the cerci shows the "harpoon" shape, making this either Beaverpond, or Harpoon (G. descriptus). S8 has a small dorsal yellow mark, and that matches the picture in Blair Nikula's book (1) of Beaverpond, while Harpoon doesn't have any markings on S8.
