Moved from Damselflies.

This does look like Tule Bluet (Enallagma carunculatum). Although the focus isn't perfect for looking at the cerci in this picture, they do look like what I would expect for Tule. The cerci look too big for Boreal, Northern, or maybe Alkali Bluet. Those three are the only other bluets that might have this much black on the abdomen (aside from the mostly black bluets, of course). The eyespots are too small for Boreal/Northern, too, and the black humeral stripe is too wide for Alkali.

Not an Argia, an Enallagma. Could be Tule, as suggested, or Familiar, Northern... you need to look at the male's claspers under a hand lens.
