=toc= =Supplies= 1. Net 2. Waders 3. A chart to sort the organisms by 4. Containers to separate different organisms 5. Tweezers 6. Paintbrushes or another utensil to sort through the debris (Make sure three or four people have waders) 7. A river of flowing water of some kind. (This is a picture of the chart to sort the organisms, tweezers, and paintbrush) =Steps= 1. Send the people with waders into the water with one person holding the net.

2. Have that one person set the net down, and the others should put rocks on the end of the net so it stays down.

3. The others not holding the net will kick around in the sediment and rocks until enough debris is collected in the net.

4. Once there is enough in the net, remove the rocks and lift the net from the bottom so that nothing falls out. 5. Bring the net out of the water and onto the land. 6. Using the paintbrush and tweezers, have people gather around the net, look for any moving objects. 7. Using tweezers, capture the creatures and place them in a bin of water. 8. After all the creatures have been captured, sort them by species. Make sure the crayfish aren't with the other species because they'll eat the others! 9. Place all the same kind of species in smaller containers together. 10. Identify and count each critter. 11. Record the information of the critters. 12. Release all the critters back into the stream. 13. Make sure they are released down stream so they do not mess up the data.
