Explore general as well as scientific information about the movement, chemistry and biology of area surface and ground water environments.
The following data are summarized as seasonal average values for lake and river sampling locations located within the watershed. While these data are useful to serve as a general picture of watershed health, these data must be viewed with caution because these samples have been taken from ecologically different water resources.
