The English River Thames is navigable from Cricklade or Lechlade to the sea, and this part of the river falls 71 meters (234 feet). There are 45 locks on the river, each with one or more adjacent weirs. These lock and weir combinations are used for controlling the flow of water down the river, most notably when there is a risk of flooding, and provide for navigation above the tideway.
Teddington Lock is a complex of three locks and a weir on the River Thames between Ham and Teddington in the London Borough of Richmond upon Thames, England. Historically in Middlesex, it was first built in 1810.
Marsh Lock is a lock and weir situated on the River Thames in England, about 1 mile upstream of Henley Bridge in Henley-on-Thames, Oxfordshire. The lock is close to the Berkshire bank, but accessed from the Oxfordshire side via two long walkways, the downstream one being near Mill Meadows. The first pound lock was built by the Thames Navigation Commission in 1773.
Sonning Lock is a lock and associated weir situated on the River Thames at the village of Sonning near Reading, Berkshire, England. The first lock was built by the Thames Navigation Commission in 1773 and it has been rebuilt three times since then. There is a weir a little upstream at the top of the island where Sonning Backwater separates from the main course of the river.
The Thames Path is a National Trail following the River Thames from its source near Kemble in Gloucestershire to the Woolwich foot tunnel, south east London. It is about 185 miles (298 km) long. A path was first proposed in 1948 but it only opened in 1996.
Chertsey Bridge is a road bridge across the River Thames in England, connecting Chertsey to low-lying riverside meadows in Laleham, Surrey. It is 550 yards (500 m) downstream from the M3 motorway bridge over the Thames and is close to Chertsey Lock on the reach above Shepperton Lock. The bridge is a seven-arch tied arch white stone bridge built 1783–85 and is a Grade II* listed building. It has a weight restriction of 18 tonnes for LGVs.
The Thames Conservancy was a body responsible for the management of the that river in England. It was founded in 1857 to replace the jurisdiction of the City of London up to Staines. Nine years later it took on the whole river from Cricklade in Wiltshire to the sea at Yantlet Creek on the Isle of Grain. Its territory was reduced when the Tideway was transferred to the Port of London Authority in 1909.
Hambleden Lock is a lock with a long weir situated on the River Thames in England, about 2 miles downstream of Henley Bridge. The lock is on the Berkshire bank between Aston and Remenham. Built by the Thames Navigation Commission in 1773, the lock is named after the village of Hambleden, a mile (1.5 km) to the north.
Iffley Lock is a lock on the River Thames in England near the village of Iffley, Oxfordshire. It is on the southern outskirts of Oxford. The original lock was built by the Oxford-Burcot Commission in 1631 and the Thames Navigation Commission replaced this in 1793. The lock has a set of rollers to allow punts and rowing boats to be moved between the water levels.

Staines Boat Club is a rowing club between Penton Hook Lock and Bell Weir Lock on the River Thames in England. The club was founded in 1869 when it was first listed in the Rowing Almanac as racing in that season. Its boathouse formally reopened in May 2022 after renovations. It is located next to the Hythe spur of the Thames Path in Egham Hythe, historically also known as Staines hythe, the last word meaning small harbour or river harbour.
Marlow Lock is a lock and weir situated on the River Thames in the town of Marlow, Buckinghamshire, England, about 300m downstream of Marlow Bridge. The first pound lock was built by the Thames Navigation Commission in 1773.
Sunbury Lock is a lock complex of the River Thames in England near Walton-on-Thames in north-west Surrey, the third lowest of forty four on the non-tidal reaches. The complex adjoins the right, southern bank about 1⁄2 mile (0.80 km) downstream of the Weir Hotel.
Chertsey Lock is a lock on the River Thames in England, against the left bank, an area of Green Belt including Laleham Park, the largest public park in Spelthorne. It faces the town of Chertsey and is the fifth-lowest of the forty-four locks along the non-tidal course of the river. Owing to a course alteration both banks at the site of the lock have been since medieval times in Surrey. Stone-built Chertsey Bridge built in 1785 is 210 m south (downstream) of the lock. The lock was built by the City of London Corporation in 1813, lengthened in 1893 and again in 1913.
Staines Railway Bridge carries the Waterloo to Reading Line across the Thames in England.
Bell Weir Lock is a lock on the River Thames in England by the right bank, Runnymede which is a water meadow associated with Egham of importance for the constitutional Magna Carta. It is upstream of the terrace of a hotel and the a bridge designed by Edwin Lutyens who designed an ornamental park gate house along the reach. The bridge has been widened and carries the M25 and A30 road across the river in a single span. The lock was first built by the Thames Navigation Commission in 1817; it has one weir which is upstream. The lock is the eighth lowest of forty-five on the river and is named after the founder of the forerunner of the adjoining hotel who took charge of the lock and weir on its construction.
Boveney Lock is a lock on the River Thames situated on the Buckinghamshire bank opposite the Windsor Racecourse and close to Eton Wick. Boveney is a village a little way upstream on the same side. The lock was first built in 1838 by the Thames Navigation Commission. The lock was rebuilt in 1898 closer to the Buckinghamshire bank, and a set of boat rollers were installed on the old site.
Penton Hook Island is a mainly wooded former peninsula created into a series of three weir-divided islands in the River Thames in England, so created in river modifications since 1815 with a navigable lock and weir stream channel to form meander cutoffs. It has a lock and weirs that are the divide between the Laleham Reach, above Chertsey Lock and Staines Reach, above Penton Hook Lock.
The Abbey River is a right-bank backwater of the River Thames in England, in Chertsey, Surrey — in the town's northern green and blue buffers. The L-shaped conduit adjoins mixed-use flood plain: water-meadows landscaped for a golf course, a motorway and a fresh water treatment works on the island it creates, Laleham Burway to its east and north in turn. Its offtake from the Thames is at the apex of Penton Hook, Staines upon Thames below its lower weir close to the Chertsey-Thorpe boundary in the Borough of Runnymede. Its outfall is the weir pool of Chertsey Lock back into the Thames, visible from Chertsey Bridge. The Environment Agency plans to build similar channels to the upstream Jubilee River, one of which will intersect the watercourse, another of which will be close to its outfall, thereby compensating for loss of its historic bypass functions.
