This is my infographic of river study. On camp we tested the Pohangina river. We had an expert come to talk to us about river testing.We had to check how clean the water was, find good macro invertebrates, smell the water and check if there was enough algae to feed the macro invertebrates. We are now experts at river testing. My infographic tells you about macro invertebrates, water smell, water clarity, algae, environment around the river and what you need to river test.
