- Oh no, the red flag is up so I can't go in the river. I wonder why there is a red flag. It rained, well that's not a good enough reason for me. I am going to research and see what happened.

- There is gross bacteria in the water that makes it dangerous to be in the water. This gross bacteria comes from CSOs and Stormwater runoff. When it rains a lot the rain washes pollutants, poop gasoline and other nasty stuff into the river. When it doesn't rain the river becomes shallow and hotter.
- When this happens nutrients are concentrated and cyanobacteria or E. Coli bloom. Due to combined sewage overflow or CSOs the rivers health declines by 20% which means it is less safe for humans and the animals that make up the rivers ecosystem. That is why right after and for a few days after it rains heavily or theres a drought you can't go in the river and they put up a red flag

- Wow I learned so much! I hope those poor animals in the river are okay. I am going to do my best at helping in reducing CSOs. I want to be a scientist when I am older.
