The Chedoke Creek and its many tributaries flow through a highly urbanized area of Hamilton. It is considered the most contaminated subwatershed of Hamilton Harbour. Chedoke is contaminated with raw sewage, likely from cross-connections between residential sanitary and storm sewers on Hamilton Mountain. The headwaters (the source) are found above the Niagara Escarpment, with only three tributaries present above the surface; a significant portion of the Chedoke watershed has experienced intense urban development over the years. As a result, the majority of the water flow directly results from stormwater input. The mouth of the creek empties out into Cootes Paradise and subsequently, Hamilton Harbour, along a now-canalized channel.
