Southampton Water in the context of Weston, Southampton

The River Itchen in Hampshire, England, rises to the south of New Alresford and flows 26 miles (42 km) to meet Southampton Water below the Itchen Bridge. The Itchen Navigation was constructed in the late 17th and early 18th centuries to enable barges to reach Winchester from Southampton Docks, but ceased to operate in the mid-19th century and is largely abandoned today.

The river is one of the world's premier chalk streams for fly fishing, amenable to dry fly or nymphing. The local chalk aquifer has excellent storage and filtration and the river has long been used for drinking water. Watercress thrives in its upper reaches.

Southampton is a port city and unitary authority in Hampshire, England. It is located approximately 80 miles (130 km) southwest of London, 20 miles (32 km) west of Portsmouth, and 20 miles (32 km) southeast of Salisbury. Southampton had a population of 253,651 at the 2011 census, making it one of the most populous cities in southern England.

Southampton forms part of the larger South Hampshire conurbation which includes the city of Portsmouth and the boroughs of Havant, Eastleigh, Fareham and Gosport. A major port, and close to the New Forest, Southampton lies at the northernmost point of Southampton Water, at the confluence of the River Test and Itchen, with the River Hamble joining to the south. Southampton is classified as a Medium-Port City.

The Borough of Eastleigh is a local government district with borough status in Hampshire, England. It is named after its main town of Eastleigh, where the council is based. The borough also contains the town of Hedge End along with several villages, many of which form part of the South Hampshire urban area.

The neighbouring districts are Fareham, Winchester, Test Valley, Southampton and (across Southampton Water) New Forest. Water bounds much of the borough, with Southampton Water and the River Hamble bordering the east and southwest of the district. The borough lies within the Hampshire Basin.

The Itchen Bridge is a bridge over the River Itchen in Southampton, Hampshire. It is a high-level hollow box girder bridge. It is located about a mile from the river mouth. The bridge spans 870 yards (800 m), is 92 feet (28 m) at its highest point and weighs 62,000 tons. The bridge connects the A3025 Portsmouth Road to Southampton. It was built to replace the former chain ferry, known as the Floating Bridge, that crossed the river at that point. The bridge's set of blue energy-saving lights can be seen from up to 5 miles (8 km) down Southampton Water from the bridge.

The bridge has achieved notoriety as a venue for suicide, with over 200 alleged suicides recorded since its opening in 1977, prompting calls for the construction of preventive measures along its length.

The River Test is a chalk stream in Hampshire in the south of England. It rises at Ashe near Basingstoke and flows southwards for 40 miles (64 km) to Southampton Water. Settlements on the Test include the towns of Stockbridge and Romsey. The river's valley gives its name to the local government district of Test Valley. Below the village of Longparish, the river is broadly followed by the Test Way, a long-distance footpath.

Much of the Test is a 438-hectare (1,080-acre) biological Site of Special Scientific Interest. It is part of the Solent and Southampton Water Ramsar site and Special Protection Area. The river is used for fly fishing for trout from its source to its tidal limit.

The River Hamble in south Hampshire, England, rises near Bishop's Waltham and flows for 10.1 km (6.3 mi) through Botley, Bursledon, and Lower Swanwick before entering Southampton Water between Hamble Common and Warsash.

The river is tidal for about half its length and is navigable below Botley. From the medieval period to the present it has been a major ship and boat-building area. Leisure craft are still built by the Hamble today. One of the main builders was Luke & Co, later Luke Bros, from around 1890 to its closure in 1945. The lower reaches are a major yachting area with easy access to the sheltered waters of Southampton Water and The Solent.
