The canal receives water from the Skookumchuck River and other smaller tributaries. It is also fed by the Mayfield Dam, which regulates the flow of water into the canal. The flow of water in the canal is generally higher in the spring and winter months, due to increased rainfall and snowmelt. One interesting fact about the canal is that it was originally constructed to provide water for a coal-fired power plant in Centralia, but the plant has since been decommissioned. Despite this, the canal continues to play an important role in the region's hydrology.
