For Students
Can you tell the difference between a damselfly and a mayfly?
We can help. If you want to identify an aquatic macroinvertebrate you found in a stream, check out our macroinvertebrate key.
You can also view a photo gallery of more than 50 aquatic invertebrates.
Are you a water wizard?
You can test your water awareness with our quick quiz, then follow the links for more detailed information about water issues.

Leaf Pack Network®
Would you like to know whether your local stream is healthy? Ask your school to join the Leaf Pack Network®!
Your school can conduct a leaf pack experiment and share the data through the network to show the important connection between streamside forests and the ecology of rivers and streams.
