What is the volume of water flowing down river thames?

The average flow rate of the River Thames is approximately 196 cubic meters per second (m³/s) at Teddington Weir, which is located near the tidal limit of the river. This means that on average, around 196 cubic meters of water flows past Teddington Weir every second. However, the flow rate of the river can vary significantly depending on factors such as rainfall, snowmelt, and releases from reservoirs upstream. During periods of heavy rainfall or snowmelt, the flow rate can increase substantially, while during dry periods, it can decrease significantly.
