The mini stream assessment scoring system (miniSASS) is a simple citizen-science tool for monitoring the water quality and health of streams and rivers.
Work through the river in this order:
A red star * means you must answer that question.
Some totals and averages are worked out for you and shown as read-only fields.
You can tap Back to fix any answer before you submit.
