How can  we help Bowker Creek? Well, a start for  this would be to  educate yourself and learn more about th creek's ecosystem and what we can do to help. Bowker Creek is a possible home for amazing animals, these animals (such as the Coho salmon) used to live here. And they can live here again if we just clean up the creek and create a safe environment for new species.

Bowker Creek is around 14-1,1500 years of age. Bowker Creek is named after John Sylvester Bowker, an American settler who came to Oak Bay in the 1860s. Bowker Creek runs from the wetland on the University of Victoria campus through the District of Saanich and the City of Victoria, and discharged to the sea through the District of Oak Bay.

Runoff causes water pollution because it sometimes includes debris, chemicals, and other pollutants picked up by the rain. Fluids from the roads around Bowker creek go through storm drains, and the toxins are bad for the water. We need to make sure our watershed produces unpolluted runoff to increase the creeks water quality.

How long will the restoration take?
By OB16
Many watersheds have a base document Integrated Storm Water Management Plan (ISMP). The Bowker Creek Blueprint: The Hundred Year Action Plan to Restore Bowker Creek Watershed,; is the intiative's unique verion of an ISMP. The restoration will significantly increase overall creek health by improving water quality, habitat, and flow conveyance.

How will we maintain it once it’s restored?
By OB16
It's very important to maintain a natural Bowker Creek. There are many easy ways to do our part, for starters, we would have to carefully watch the growth of invasive plants. We should also watch the pH levels of the water, and not use fertilizers in our gardens, to prevent toxic runoff. Also, spreading awareness can go a long way for the creek.

The Mallard Duck is always a constant visitor anywhere along a marsh or wetland or a ocean. Males have a dark green head and a yellow bill. Females are brown with blue feathers under their Wings. They eat the seeds of aquatic plants, seeds, stems, and insects when they are young. A great place to see them is at Beacon Hill Park or Bowker Creek.

Salmon Living Conditions & Water Quality
By OB O
Salmon need pristine water to live in Bowker Creek. If we want the salmon to return, then Bowker Creek shouldn't remain as a drainage system. Because the run-off of human chemicals can harm the salmon.

Mallard Duck Diet
By OB O
Mallard ducks eat small crustaceans, grasses, and weeds. Ducks will also eat small sticklebacks and fish eggs, which is bad for salmon.

Aggresion Between Species

Here is a video clip of a Mallard duck feeding on salmon eggs in a spawning pool. The salmon then proceeds to attack the duck, defending its young.
