There is the eastern mudminnow, they are native to your neck of the woods. Very closely related to the central mudminnow. I have caught the eastern mudminnow in several locations. Mostly lowlands where there is a TON of vegetation and swampy. However I have caught some in one small stream that runs into a heavily vegetated section of river. From what I understand, the eastern mudminnow is native to the Atlantic Slope drainages where as the central mudminnow is native to the Mississippi drainages.
I caught a couple dozen easterns and placed them in a pond but never saw them again. The pond was well vegetated, but I think they fell prey to the bass before they could reproduce. I suspect if you caught a large enough number of them or stocked them before bass were established they would make a good introduction.
Banded killifish also know as bull minnows are great pond fish. They would probably do well in your Adirondack pond... I know of a few commercial hatcheries that sell them as well. They are egg layers but other than that are in many ways like overgrown mosquitofish(gambusia). They hug the surface and tend to stay very shallow. They are hardy as well and make great bass bait.
The eNature website
http://www.enature.com/fieldguides/intermediate.asp?curGroupID=3 is good, they don't have every species listed but have most. Another one I like is the EFISH website by VA Tech
http://www.cnr.vt.edu/efish/ Although it is geared for VA fishes, most species found in VA are found throughout the south and Midwest.
