Welcome to the Secret Life of the Stream Health
Index!
 This
simple Stream Health Index graphic belies the complexity of
the information that goes into it. An index brings information
from multiple sources together into a single number, like
a grade, that can be understood at a glance.
The following pages walk through the process
from data gathering to index calculations. You can click on
"next" at the bottom of each page to go through
all four sections.
