 The tributaries gradually merge as Tai Po River, which parallels the Tolo Highway until Tai Po Market KCR Station, where it turns north to meet the Lam Tsuen River.Before the 1970s, Tai Po River flowed straight into Tolo Harbour near Tai Po Market Station.However, due to the pressing need for development land in the then new town of Tai Po, land was reclaimed, and the Tai Po River lengthened northwards to flow into the Lam Tsuen River before it enters Tolo Harbour.
