Monitoring Tatalu’s water quality

When you imagine a river, what do you see? Perhaps you hear the sound of water crashing over rocks or notice the clarity of the stream, revealing fish swimming along its current. Rivers like the Little Campbell River hold a quiet kind of power by offering a peaceful escape, a break from the digital chaos of modern life. 

Known as Tatalu to the Semiahmoo First Nation, the Little Campbell River’s watershed is home to diverse wildlife, including some endangered species. Maintaining the health of this river is crucial, not only for its ecosystem but also for activities like shellfish harvesting in the bay. 

A Rocha Canada’s Conservation Science team at the Brooksdale Environmental Centre has been monitoring the river’s water quality for many years. They gather data on key factors like pH, dissolved oxygen, temperature, conductivity, depth, turbidity, and bacterial and chemical contamination. This data, collected from many sites, helps assess water quality changes over time, including seasonal and daily fluctuations. The data then directly informs environmental management decisions that will protect and improve the river’s health.
