Nice pics! Definitely female.
After digging around on the web a bit, I believe it to be
Cambarus bartonii, but I'm not certain. I'd say you'd have a better chance of getting a better I.D. over on the bluecrayfish forum, but I know they're gonna wanna see male form I gonopods for a more positive I.D. Still, I'd post there if you're really curious to find out exactly what it is.
Now go catch some more so we can see what else is out there!
