I believe what we have are newts.
Mudpuppies or waterdogs are found in streams around here though.
When I was a kid visiting my grandparents in Catawba, NC, we used to catch good numbers of salamanders running about 2-3" long in shallow pools in a local branch and put them on set-hooks for catfish in a nearby creek. It was almost as much fun to catch the spring lizards and helgramite larvae for bait as the catfish.
