As well as the obvious dangers to health presented by sewage, which is likely to contain a variety of Bacteria and other micro-organisms harmful to Human health, sewage provides a source of nutrients which can lead to eutrophication and the rapid growth of blooms of Algae, Bacteria or other micro-organisms, which absorb oxygen from the water leading Fish and other aquatic organisms to asphyxiate.

Paddne Creek was culvertized (covered and channeled through a concrete culvert) in the late nineteenth century) but has recently undergone restoration work intended to return it to a natural state, both to improve the local habitat and to provide a run for Salmon and Trout, which historically used the creek to access Padden Lake and the waterways which supply it. Officials involved in the project have describes the spill as 'disheartening'.
