Welcome to the big one (RCP size wise). This unassuming outfall, where the creek in which the drain carries reconnects with its natural course, does not do it justice. This big-boy travels 5km+ under the streets of Toronto, and carries only a trickle of water that it was designed for. Big grilles let in natural light every few KM along the winding 4m+ high RCP. A bike would surely be a handy tool for exploring this monster, and save you from the rubber-boot induced foot sores!
