In our experiment we surveyed the presence of the Virile Crayfish Orconectes virilis in Quail Creek and Quail Creek Reservoir. While surveying the determined stations we saw lots of crayfish within the campground itself and lots of evidence below the campground in the reservoir. We found lots of other macroinvertebrates, such as dragonfly nymphs, in higher pools. Because there was no connectivity between higher pools the crayfish were likely inhibited from migrating further upstream. In the stations where crayfish were found there were many similarities between terrestrial and aquatic flora and fauna that possibly contribute to the survival of the crayfish.In higher pools with little to no connectivity, the ground level sediment was hard sandstone that would likely inhibit burrowing and hibernation of any crayfish that did happen to make their way upstream terrestrially. This could be an area of further study.
