Moved
Moved from Whitefaces. Comment from Dennis Paulson, forwarded by William Edwards: "I agree entirely with you that it is Leucorrhinia intacta. The epiproct is diagnostic, and the fact that the middorsal carina on the front of the thorax is pale is also indicative of this species when immature. Immature males have an abdominal pattern much like that of females until they turn black. Young male Hudsonian Whiteface would look about like this but wouldn't show a widely forked epiproct like that."

In my opinion - Dot-tailed Whiteface (immature male)
According to (1) - for the species Leucorrhinia intacta:
The epiproct (the abdominal appendage below the two cerci) is bifurcated (forked) with the lateral margins widely divergent posteriorly. You can see the two tips of the epiproct sticking out on the sides of the cerci in your dorsal view photo.
There is a picture of the epiproct in (1) on pg. 690


The forked epiproct is somewhat visible in this photo.
