These include a variety of structures connected with use of the river, such as navigations, bridges and watermills, as well as prehistoric burial mounds.A major maritime route is formed for much of its length for shipping and supplies: through the Port of London for international trade, internally along its length and by its connection to the British canal system.) is a river that flows through southern England, most notably through London.
In Scotland, the Tay achieves more than double the average discharge from a drainage basin that is 60% smaller.
Along its course are 45 navigation locks with accompanying weirs.
It boasts great views of the SS Great Britain, the floating harbour and passing boats from the top deck. Food nights include Wednesday pie and a pint, Thursday steak club and Sunday roasts.
Other activities include a Monday night quiz, a Tuesday Open Mic night and live music on Thursdays in the downstairs Hold Bar.
Rowing and sailing clubs are common along the Thames, which is navigable to such vessels. Major annual events include the Henley Royal Regatta and the Boat Race, while the Thames has been used during two Summer Olympic Games: 1908 (rowing) and 1948 (rowing and canoeing).
Safe headwaters and reaches are a summer venue for organised swimming, which is prohibited on safety grounds in a stretch centred on Central London.
It rises at Thames Head in Gloucestershire, and flows into the North Sea via the Thames Estuary. Its tidal section, reaching up to Teddington Lock, includes most of its London stretch and has a rise and fall of 7 metres (23 ft).
Running through some of the driest parts of mainland Britain and heavily abstracted for drinking water, the Thames' discharge is low considering its length and breadth: the Severn has a discharge almost twice as large on average despite having a smaller drainage basin.
It also flows through Oxford (where it is called Isis), Reading, Henley-on-Thames and Windsor.
The lower reaches of the river are called the Tideway, derived from its long tidal reach up to Teddington Lock.
Ordnance Survey maps still label the Thames as "River Thames or Isis" down to Dorchester.
