Before the building of the Teddington Lock in 1811, the river was tidal for 16 miles upstream by way of tidal activity from the North Sea.
Today the river is entirely tidal for the 55 miles from it's estuary at Southend until it reaches the weir and three locks at Teddington. This part of the river is known as The Tideway, an area that includes the Thames Estuary, The Thames Gateway and the Pool of London. It is at London Bridge where the river has a has a depth of 1.8 metres, that is the basis for the the publication of the London Tide Tables.
The river receives two tides a day, with levels as high as 24 feet, which takes up to 4 - 5 hours to flow in and between 6 - 9 hours to drain out. Because of this the river is vulnerable to flood and storm surges. Due to this the Thames Barrier was constructed in 1974, the world's second largest floating barrier, built on a 570 yard stretch of the river at Woolwich.
The river's discharge at the site of it's estuary has a catchment area of 4,994 square miles, along with that of the River Medway, whose estuary is also situated in the same area.
