The depth of the River Thames varies significantly along its course. In central London, for example near London Bridge, the river is relatively shallow at about 1.5 meters (5 feet) deep. However, as the Thames moves eastward into the estuary where it meets the North Sea, the depth increases considerably, reaching around 20 meters (66 feet) at its deepest point. The depth fluctuates due to tides, rainfall, and human activities such as dredging. At certain locations like Woolwich, the depth can be about 6.5 meters even at low tide, showcasing how variable the river depth is along its length.
