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.

This way to the wizard!

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.
