We are from La Center High school

Where do we Test? We test on a tributary of the East Fork of the Lewis River called, Brezee Creek.

Our Hypothesis If Brezee Creek is viable for salmon then the temperature should be between 54 F-65F turbidity should be above 10NTU Dissolved Oxygen should be more than 9 ppm (parts per million) and pH should be 7-8 because salmon are intolerant to poor water quality.

Turbidity CM Turbidity is the amount of sediment the water. Having a lot of sediment in the water can suffocate salmon, especially the eggs.

Temperature Temperature is an important aspect of salmon life because having a temperature too high or too low will be an unviable habitat for salmon This chart shows the temperatures we had as an average for the two sites we test each month.

Dissolved Oxygen PPM (parts per million) Dissolved Oxygen is the amount of oxygen in that’s in the water. Having fast moving water can help get the oxygen in the water like when you see rapids or the white caps in a stream.

pH pH is how acidic or alkaline the water is, salmon need pH to be between 7 and 8 to be considered healthy for salmon

What have we done? The importance of salmon to us is that the Environmental Studies Class at La Center School has monitored a remote site incubator for salmon for the past four years and worked with Les Greear, our Fish First salmon restoration guide to install, monitor, and care for 1000 chum salmon at our RSI. Les guides us through the process of connecting 300 feet of pipeline to a trough and incubator staged by Brezee Creek. Our chum salmon were delivered by our Washington Department of Fish and Wildlife contact Jim Byrnes at the end of March. We cared for our salmon by cleaning the RSI every day to ensure that our salmon survived. We released our Coho salmon from our fish tank provided by the Salmon in the Classroom program and our chum salmon from the RSI with Mr. Sloniker from La Center Elementary and his fourth grade science classes into Brezee Creek.

What is the Importance? The importance is keeping our streams a viable habitat for not only salmon but all of the wildlife in our wetlands. The wetlands need to be healthy so it can filter pollutants out of the water.

Special thanks Judy Bufford- water testing mentor from the Water Resource Education Center Fish First- salmon restoration organization Les Greear- salmon restoration guide from Fish First Washington Department Fish Wildlife/ Washougal Fish Hatchery- for providing us 1000 Chum salmon eggs Columbia Spring’s Salmon in the Classroom Program- providing Coho salmon eggs Clark County Environmental Services

Are there any questions?
