Description of specimen

On 6/9/18 and 9/23/18, I found many adult and juvenile ringed crayfish at the Camp Creek site and juveniles downstream in Mill Creek (the lat long is of the Camp Creek site). The Camp Creek site is part of reference temperature project and I have been monitoring it every summer since 2006.
