Did you know that very small - often microscopic - aquatic animals can tell us a whole lot about the quality of the water in places like rivers, streams, lakes and ponds? Drop in on this Discovery Station to find out more, and to even view some water samples from the nearby Hassayampa river and Palm lake through one of our microscopes. See what you can find! No need to register; just come on in between 10:30am-12:30pm.
