EPA's Watershed Academy offers a variety of
self-paced training modules that represent a basic and broad introduction to the watershed management
field. The Watershed Ecology module
is an excellent introduction to watershed and stream science.
This document known as the RBP manual is the “bible” for most initial assessment programs.
This document has a very nice section on stream health which was produced for Oklahomans but is equally relevant to northern Minnesotans.
View the stream section or get the full on-line report that includes lakes and reservoirs and wetlands and non point source
pollution.
This excellent website was produced by Cristi Cave, a former fisheries
student from the U. of Washington and is very well done and useful to a variety of age groups. She has managed to keep it on-line
and add to it for many years.
