There are a nearly endless lists of things to help the creeks clean up but a few of them are: Filtration of storm drain before it’s released to a water source. Stop illegal dumping and littering. And reduce sediment from streets into the creek especially from construction sites

The creek is also home to these unpleasant creatures. Known commonly as a Leech, this creature consumes the blood of its prey by latching onto it with its Anterior and Posterior sucker. Leech bites do not hurt and are actually used for medical purposes in some places. Uses like healing wounds and unblocking clogged blood veins

Bowker Creek is full of these little creatures called Platyhelminthes, better known as “Flatworms”, these creatures feed on Protozoa and Bacteria and are generally consumed by a variety of small species including Spotted Mandarin and Yellow Wrasse.

Bowker Creek is a slightly polluted stream, being home to a few select resistant species. One of which, is the Three-Spined Stickleback. The Three-Spined Stickleback has a higher tolerance to pollution than most smaller fish. This organism proves to be a food source for many of the creeks inhabitants

Year number one was the year of planning, where students and staff alike came together to design the area based on what the school thought would be an asset.

Bowker creek at this time can only support smaller, more toxicity resistant organisms. A variety of small fish, leech, worms, parasites, insects and other little species thrive here.

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
