We are Grade 6 students monitoring the health of our local stream and river. The data we collect is used by the Department of Fisheries and Oceans to help manage and protect salmon and their habitat. We also want to share what we find with other members of our community – the Vedder River and Peach Creek are really popular places for people in Chilliwack to go fishing, walking, biking, horseback riding, birdwatching and swimming. All these different people should know about the salmon that share the water with them. In order to share this information, we post everything we learn to our website and share our photography on Instagram. In the spring, we will post signs with our latest results on bulletin boards along the trail, as well as tips for how to enjoy the river and creek without harming the salmon. Water Quality Sampling Temperature Credit: https://www.pskf.ca/publications/Module03.pdf We measure temperature because different living things thrive in different water temperatures. Also, the temperature of the Vedder watershed has been in the news the past few summers because it is getting close to being harmful to spawning salmon. We use a digital meter to measure the temperature. Dissolved Oxygen Most animal life in the water depends on dissolved oxygen – the amount of oxygen contained in the water. A healthy stream should have dissolved oxygen between 85% and 110%. We use a meter to measure the dissolved oxygen. pH pH is a measure of how acidic or alkaline the water is. Human activity like farming, industry, and emissions can affect the pH of a stream. Credit: https://www.pskf.ca/publications/Module03.pdf Turbidity Turbidity is a measurement of the cloudiness caused by sediment, microscopic organisms, and pollutants. It can affect the plants and algae that grow in a stream, and high turbidity can clog the gills of aquatic animals. Phosphates Many fertilizers are high in phosphate. If too much fertilizer runs-off of fields and into streams, it can affect the amount of algae growth, which, when the extra algae eventually dies, can lead to a low oxygen environment. This is called eutrophication (Wow, big science word!) Fish Trapping We also catch, identify and measure fish. This helps us understand how many fish are hatching in the stream, and how many are surviving until they are old enough to swim downstream to the ocean. Invertebrate Sampling In the spring, we will catch and release the bugs and other critters that share the stream with the salmon. This helps us to know what they might be eating, and also gives us information about the overall health of the stream. For more information about stream keeping, visit the Pacific Stream Keeping Federation, which is where we found most of our information.
