Where do we come from?Where do we come from?We attend La Center High
School. Which is located North of Vancouver.
What Do We Do? What Do We Do?
• Test water with two fourth grade classes• Take record of each day tested• Raise 1000-2000 ChoHo and
Chum eggs• Release our salmon into our
watershed
HypothesisHypothesis
If the dissolved oxygen (ppm) and turbidity (cm) are high then there is a higher probability of salmon survival because the water would be breathable and there is less sediment.
What is Dissolved Oxygen?What is Dissolved Oxygen?The saturation of oxygen in water.Why is Dissolved Oxygen Why is Dissolved Oxygen
Important?Important?D.O is what allows the Fish to breath and
makes it easier for decomposition of matter in the water.

Our dissolved oxygen levels for both sites showed that our creek was
suitable for the salmon population
What is Turbidity?What is Turbidity?
Turbidity indicates the amount of suspended Turbidity indicates the amount of suspended sediment in the water.sediment in the water.
Why is Turbidity Important? Why is Turbidity Important? High turbidity can have negative effects to aquatic High turbidity can have negative effects to aquatic life, such as suffocation due to the high amounts of life, such as suffocation due to the high amounts of

The turbidity levels show that the sediment level was very low in Brezee Creek. Turbidity can also be measured in NTU’S (Nephelometric Turbidity Unit)
