Based on your photos and location, it is almost certainly a Johnny darter, which is one if not the most common darter species. It is most common in stream habitats, but can adapt to ponds, especially those that are clear with rocky/sand bottoms. I have experimented with a closely related eastern relative, the tessellated darter.
