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

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)
