Cambarus
Excellent photos! Based on the absence of cephalic spine, the single row of tubercles on the mesial margin of the palm of the chelae, the wide open areola, the acute suborbital angle, the rostrum shape as well as the general appearance and your location, this is most likely
Cambarus bartonii
. And yours is a female - note the annulus ventralis on the ventral photo.
Now having said all of that, the Cambarus genus is still being sorted out, with some lumping into complexes and others declaring new species/subspecies, so without a doubt, the taxonomy will provide new surprises down the road. And
bartonii
is one of those looking like a complex. However, in your area
bartonii
hasn't been
too much
of an issue, so I think we can safely assign that ID to your specimen. If we have to later move to a lower taxon (subspecies), it's no problem.
Again, great photos - I was able to see pretty much everything I needed to make a good ID.
