This field guide is designed to help riverwatchers
1) identify aquatic phenomena and environmental concerns;
2) collect the information needed to report their observations, and;
3) connect with the proper agencies and organizations with these questions and concerns.
Riverwatchers should consider potential sources and causes of observed phenomena. In a river system, causes can come from activities on land (e.g. deforestation, development/construction), areas upstream, and be the result of events that have happened recently (e.g. water releases from dams, heavy rains and wind).
