pos: River Thames and Teddington Lock, the river forms part of the Port of London and navigation is administered by the Port of London Authority. Both the tidal river through London and the non-tidal river upstream are intensively used for leisure navigation. The non-tidal River Thames is divided into reaches by the 45 locks. The locks are staffed for the greater part of the day, but can be operated by experienced users out of hours. This part of the Thames links to existing navigations at the River Wey Navigation, the River Kennet and the Oxford Canal. All craft using it must be licensed.

pos: Thames Path Lock building by the Thames Commissioners had improved the whole river navigation from Inglesham to the upper limit of the tidal reach at Staines by 1789. On the tidal Thames below Staines, six new locks were built by the City of London Corporation to improve the navigation between 1811 and 1815. There is a Thames Path on both sides of the river downstream of Teddington Lock, the southern path including the original towpath as far as Putney Bridge. Due to the locks built by the City of London, the river is now tidal downstream from Teddington Lock. A further lock

Before Teddington Lock was built in 1810–12, the river was tidal at peak spring tides as far as Staines upon Thames. In descending order, non-related tributaries of the non-tidal Thames, with river status, are the Churn, Leach, Cole, Ray, Coln, Windrush, Evenlode, Cherwell, Ock, Thame, Pang, Kennet, Loddon, Colne, Wey and Mole.

As such the River Mole was similar to two other Thames tributaries, the Colne and the Cherwell, in having more than one channel in its lowest stretch. The River Mole flowed into the River Thames separately slightly further upstream at the point where Hampton Court Bridge crosses the river. However, during the early 1930s, when Hampton Court Way and the bridge were built, the River Mole was redirected to flow into the River Ember forming a widened and straightened channel. There have been further

Occasionally, flooding of inhabited areas is unavoidable and the agency issues flood warnings. Due to stiff penalties applicable on the non-tidal river, which is a drinking water source before treatment, sanitary sewer overflow from the many sewage treatment plants covering the upper Thames basin is rare in the non-tidal Thames, which ensures clearer water compared to the river's tideway.

In Tudor and Stuart times, various kings and queens built magnificent riverside palaces at Hampton Court, Kew, Richmond on Thames, Whitehall and Greenwich. As early as the 1300s, the Thames was used to dispose of waste matter produced in the city of London, thus turning the river into an open sewer. In 1357, Edward III described the state of the river in a proclamation: "... dung and

When London's sewerage system was built, sewers were designed to overflow through discharge points along the river during heavy storms. Originally, this would happen once or twice a year, however overflows now happen once a week on average. In 2013, over 55m tonnes of raw sewage was washed into the tidal Thames. These discharge events kill fish, leave raw

On the India and Pakistan borders the term also applies to the salt water inlets enclosed by mangroves. Creeks are found dispersed all along the Indian coast.
