Bowker Creek has had issues with the sewage system in the past as it follows the sewer line (as seen in the diagram above). Spills have a huge impact on water quality; high levels of nitrogen, phospherous and ammonia are associated with waste. To restore salmon, the stream needs to have a barrier preventing this, as seen in the current CRD plan.

We can tell a creeks polluted because of bio-indicators, and obvious signs of pollution. First bio-indicators are animals that help us determine how polluted water is because some animals can deal with more pollution than others. Judging by the species of aquatic life in the creek tells us its pollution levels

We took the time to analyse the water quality of Bowker creek as of late November.

   

Bowker creek is old creek in Oak Bay and some parts of Victoria from around UVIC and flows into the ocean at willows beach. It once meandered through forests, meadows, and grasslands. As well salmon used to spawn in the creek and it provided food for the First Nations people in the area

Although now the creek is heavily controlled where about 70% of the creek is in pipes. In recent years, there have been efforts to restore and bring back a cleaner creek. The limits of the restoration are visible alongside Oak Bay Secondary School

Part of the 100-year plan is to restore native vegetation on much of the creek corridor. The aim is to recreate the original creekside with as little influence from native plant species as possible. This will help create a better envrionment for food sources. Here is a stetch that has been made of possible  creek bed conditions on Shelbourne Road.
