Sorry -- Probably Northern two-line salamanders.  I had written off that species due to the lack of an obvious "stripe" on the individuals I was turning up.  However, they are one of the plethodontid species around here that associates with aquatic areas and lays eggs underwater (from what I gather from various VA websites).  

My guess is that these are subadults without the adult color development, but beyond (or toward then end) of their use of external gills.  

Rob?

Mudpuppys are great finds, but the lack of obvious gills, overall lack of girth, and the lack of reports of that species ranging into NOVA suggests an eastern redback salamander, but I'm not 100% sure on that.  Whatever it is, they're not hard to kick up around here!

Interesting, I've always been curious about darters. See them everywhere but never bothered to learn the different species.  Aren't some of them very sensitive to water quality?

I believe your salamander there is a juvenile eastern mudpuppy (think I can see the gills, but not sure). If so, they're very common. I've only once seen an adult though, the adults are nocturnal IIRC.
