When travelling upstream, keep red navigation buoys to your left and green navigation buoys to your right. Mercury (Hg) is an environmentally persistent heavy metal which can be toxic to marine life and humans. Sixty sediment cores of 1 m in depth, spanning the entire tidal River Thames between Brentford and the Isle of Grain, have been analysed for total Hg. The sediment records show a clear rise and fall of Hg pollution through history. [90] Mercury concentrations in the River Thames decrease downstream from London to the outer Estuary, with the total Hg levels ranging from 0.01 to 12.07mg/kg, giving a mean of 2.10mg/kg which is higher than many other UK and European river estuaries.

The River Thames contains over 80 islands ranging from the large estuarial marshlands of the Isle of Sheppey and Canvey Island to small tree-covered islets like Rose Isle in Oxfordshire and Headpile Eyot in Berkshire. They are found all the way from Fiddler's Island in Oxfordshire to the Isle of Sheppey in Kent. Some of the largest inland islands, for example Formosa Island near Cookham and Andersey Island at Abingdon, were created naturally when the course of the river divided into separate streams.

Changes to St Johns and Molesey reaches.Competition for the use of the river created the centuries-old conflict between those who wanted to dam the river to build millraces and fish traps and those who wanted to travel and carry goods on it. Economic prosperity and the foundation of wealthy monasteries by the Anglo-Saxons attracted unwelcome visitors and by around AD 870 the Vikings were sweeping up the Thames on the tide and creating havoc as in their destruction of Chertsey Abbey.

The decline of heavy industry and tanneries, reduced use of oil-pollutants and improved sewage treatment have led to much better water quality compared to the late 19th and early- to mid-20th centuries and aquatic life has returned to its formerly 'dead' stretches.

Two broad canals link the river to other rivers: the Kennet and Avon Canal ( Reading to Bath) and the Grand Union Canal (London to the Midlands). The Grand Union effectively bypassed the earlier, narrow and winding Oxford Canal which remains open as a popular scenic recreational route. Three further cross-basin canals are disused but are in various stages of reconstruction: the Thames and Severn Canal (via Stroud), which operated until 1927 (to the west coast of England), the Wey and Arun Canal to Littlehampton, which operated until 1871 (to the south coast), and the Wilts & Berks Canal. Researchers have identified the River Thames as a discrete drainage line flowing as early as 58million years ago, in the Thanetian stage of the late Palaeocene epoch. [36] Until around 500,000 years ago, the Thames flowed on its existing course through what is now Oxfordshire, before turning to the north-east through Hertfordshire and East Anglia and reaching the North Sea near present-day Ipswich.

Before bridges were built, the main means of crossing the river was by ferry. A significant number of ferries were provided specifically for navigation purposes. When the towpath changed sides, it was necessary to take the towing horse and its driver across the river. This was no longer necessary when barges were powered by steam. Some ferries still operate on the river. The Woolwich Ferry carries cars and passengers across the river in the Thames Gateway and links the North Circular and South Circular roads. Upstream are smaller pedestrian ferries, for example Hampton Ferry and Shepperton to Weybridge Ferry, the last being the only non-permanent crossing that remains on the Thames Path.River Thames: current conditions updated for Wednesday 8 February 2023.
