Right, same here, but ALL frogs and Toads and MOST Salamanders and Newts NEED WATER TO BREED, because the larvae have GILLS and eventually metamorphose into air-breathing adults. Adult don't NEED water, they simply must stay moist so they don't dry out, since they breathe through their SKIN......as well as lungs....or just skin in the case of Lungless salamanders.Frank,I have salamanders in my backyard and I am quite aways away from the nearest creek.I have never seen their egg clusters but I come across the salamanders regularly hile I am doing yard work.I have never bothered to identify them though.
Therefore, my suggestion

Moisture will not harm them either way, but terrestrial salamanders may drown, especially young that will be weak swimmers.
