The river looked clean to our at first glance, which means it has enough oxygen to support the natural habitat and little pollution. Looking clean and being clean are two different things so we need to run some tests to make sure. We picked three spots to take our tests. Number 1 at a bend behind Anna Jones house, Number 2 near the pool at a metal crossing, and Number 3 right of the bridge. Tests we will take- temperature, depth, pH, turbidity,conductivity, and flow rate. After the results of all these tests are in we will make our judgement on whether or not this river is clean. We didn't decide to to take any of the real special tests, we thought this information would be sufficient. Just from the naked eye you can see fish swimming all round the river. That initial observation told us a lot about the river. One it told us it had enough oxygen and two the visible pollution must of been too little to have much of an effect, we thus assumed that most of the test offered weren't necessary.

Area # Depth (cm) Temperature (Fahrenheit) pH Flow Rate(meters per second)Condutivity(ohms)

1-4 69. 67- .172--- 293.4

218- 69.9 7-.22---291.55

3-5 68.1-- 7.178-- 287.5

How to take- Depth- stick a meter stick in the spot you have have took other data, take measurement to the nearest cm. Temperature- place thermometer in same spot, wait until the temperature steadys then take it to the nearest tenth degree. pH-put pH strip in same spot, read the pH against the scale, take the nearest pH reading. Flow Rate- put together flow rate stick. Put spinner part in the river and have it face upstream. Leave for a few seconds and read the display screen for a stable reading. Conductivity-Stick conductivity sensor in river and take last step for flow rate.

Conclusion After our tests came out we thought the river is clean. Depth and flow showed us that the same water is in the river; the deeper parts and the parts wit a higher flow are just as healthy. (Relative to this river there isn't a pool of healthy or unhealthy water we have seen) The pH is perfectly neutral reading which supports maximum life. Our temperature readings are in the same range which means the river is very stable. Our conductivity readings meet standards for a healthy amount. Not one of our tests, shined our creek in a negative light
