2670:, obtained an Act of Parliament to authorise construction of the mill on the foreshore of land that he owned at Bishopstone. The first mill was completed in 1788, by which time Pelham had died. It was sold in 1791 to Thomas Barton, and the sale documents listed five pairs of stones, capable of producing 130 quarters of week each week. The new owner built a large mill with three storeys, capable of producing 1,500 sacks of flour each week, using 16 pairs of stones. The site was regularly affected by storms, with wheat and flour destroyed in 1792, while in 1820, the building was damaged and part of the dam was washed away. After 1853, the volume of flour produced gradually declined, often as a result of weather conditions, but it continued in operation until March 1883, when there was another violent storm and the new harbour at Newhaven required more water. The site which was known as 2612:

A forge was operational at the site in 1574, but was replaced by a corn mill when the iron industry declined. This was replaced by a three-storey brick and timber building at some point, which was later supplemented by a four-storey square extension with a flat roof, from which the owners, the Maryon-Wilson family, could watch cricket matches at Sheffield Park. While the navigation was in use, there was a wharf just to the north of the mill, where barges moored to deliver grain or collect produce. The mill ceased to use water power in the 1920s, when Tidy & Sons owned it, but was in use until 1940, when the War Office requisitioned it to billet soldiers in it. Much of the fabric of the building was damaged during this period, and it was only used irregularly after the war, until it was demolished in 1950, as was the hump-back bridge at the front of the building.

prevented it from draining from the levels. He also commented on the great shingle bar crossing the mouth of the river at Newhaven, which if removed would allow the water levels to be around 6.5 feet (2.0 m) lower at low tide. The brooks above Lewes Bridge became gradually drier as he progressed towards Barcombe Mill, but with almost no fall on the river, its winding course and numerous shoals hampered the drainage of the meadows. The brooks bordering the Glynde, to the east of Ranscombe, were generally at a higher level, but were affected by stagnant water lying on the surface. There was again no gradient on that river, which followed a winding course, but he was confident that if the drainage of Ranscombe could be solved, the drainage of the Laughton Levels would also be.

for navigation. At some time between 1676 and the publication of an Admiralty chart in 1698, the river flowed along the back of the shingle bar and broke through into the sea about 0.5 miles (0.8 km) further to the east, at the site of a tide mill. The outlet at Newhaven had been reinstated by 1731, when the Newhaven Harbour Commissioners were established by act of Parliament. The engineer John Reynolds carried out some work for them on the piers at the entrance to the river, and constructed a sluice across it at Piddinghoe between 1731 and 1733, working for the Drainage Commissioners, but that was short lived, as it was damaged in 1736 and taken down rather than repaired. By the 18th century the valley was regularly inundated in winter and often flooded in summer.

allow water to drain away when required. A second option involved raising the banks on all of the meadows, and constructing a separate sewer to carry surplus water from them to the sea, leaving the main river largely unaltered. The outfall sluice would have been located at Tarring Tenantry near Piddinghoe, and would contain three openings, two of 13 feet (4.0 m), each with a set of pointed doors facing in opposite directions, to prevent the sea entering the river, and to retain water in the river during dry periods. The third opening would be 14 feet (4.3 m) wide, with double pointed doors facing in both directions, so that it could additionally be used as a navigation lock at all states of the tide and river.

1950:, where the channel has been considerably modified over time, and is crossed by three bridges. Willey's Bridge is a small footbridge opened in 1965, to provide public access to South Malling church and to enable residents in housing estates built at Malling to get to Lewes. Previously, access to the church had only been available on Sundays, when owners of Malling Deanery allowed people to use their private suspension bridge, constructed in 1934, and located a little further upstream. This had in turn replaced a wooden bridge erected in 1868. The Phoenix Causeway is a larger road bridge named after the former Phoenix Ironworks, which was constructed in 1979 to provide a bypass for Cliffe High Street, and the 2594:

primarily protects agricultural land, it also offers some protection to around 2,000 properties. Following the floods of 1960, a further round of widening the channel and raising the banks below Lewes occurred, and where gravity drainage of the levels has proved ineffective, water is pumped into the river from land drainage ditches. Tidal water has been unable to enter the Laughton Level since 1973, when a dam and pumping station was constructed across the Glynde Reach at Beddingham. There are land drainage pumping stations at Stoneham, Offham, Rodmell, ET Wadham, Ranscombe, Denton and Beddingham, with an eighth station at Lewes which pumps water into the Malling Drain.

2624:. Success was fairly short-lived, as it was offered for sale in 1855, together with Molineux and Johnston's other mill at Lewes. Neither mill was sold, and the building materials from a foreman's cottage, nine other cottages, stone from the leats and two large cast iron waterwheels were sold at auction on 28 September 1857. There is some evidence for another mill further downstream, as Isfield Old Mill appears on Greenwood's map of 1823, and the 1874 Ordnance Survey map shows details of the leats, but it was not mentioned on the Tithe Apportionment of 1840, which is usually a reliable source of information. It was probably dismantled in the late 18th century. 2457:, although Hadfield only quotes 18, perhaps because there were two at Barcombe, identified as Pikesbridge Upper and Lower Lock on the 1875 map. Each was 52.5 by 13.5 feet (16.0 by 4.1 m), and the barges used on the navigation could carry 18 tons, suggesting that the channel was not as deep as Jessop had suggested, since his plan was for boats 45 by 12 feet (13.7 by 3.7 m) with a draught of 3.5 feet (1.1 m) which could carry 30 tons. Almost no records of the tolls collected are known to exist, but it appears that they were sufficient to pay interest on the money borrowed, but not to pay any dividends to the shareholders. 2478:

tolls could not be varied significantly without corresponding variations in the land drainage rates. The work on straightening and enlarging the lower river was carried out between 1791 and 1795, and Jessop's plans were overseen by a schoolmaster and civil engineer from Lewes called Cater Rand. The provision of a bridge at Southease was a requirement of the act, as the re-routing of the river divided farmland. In practice the costs to the landowners on the levels were too high, and another act of Parliament was obtained on 20 June 1800, which repealed the river tolls, and replaced them with higher tolls, to redress the balance.

variable. In particular, the brooks of Southover, Iford, Pool Bar, and Rodmell, which he called the West Levels, were badly affected as their embankments were low and poorly maintained. At high tide, the level of the river was above that in the meadows. The same applied to Ranscombe brooks, to the north of the junction between the Ouse and the Glynde, Further down river, at White Wall and Tarring, the brooks were generally dry, which he attributed to the land surface being higher, the walls being higher and well maintained, and the outfall sluices from the meadows being arranged at a lower level in relation to the river.

installed a Turner five-sack roller mill. A 60 hp (45 kW) compound engine was used to power the roller mill, while three pairs of millstones were driven by a "Little Giant" turbine. Milling ceased in 1918, and after a period of dereliction, it was used to manufacture buttons, made by slicing Italian nuts. Button production started in 1931, but the mill building was destroyed by fire in March 1939. It had been one of the biggest watermills in Sussex, but little remains apart from the four channels, while a grass mound where the main building was conceals an atmospheric

It consists of three bowspring arches, one fixed and the other two mounted on a central pivot. It was manually operated by a capstan mounted on the movable section, and is a rare example of its type, which are more normally found in docks and industrial areas. In 1988, Parliamentary approval was obtained to fix the bridge in position, as it had not been opened since 1967. The river finally reaches 2418:

the navigation was open from Lewes to Sheffield Bridge, and some work on increasing the size of the channel had been carried out between there and Hammer Bridge. The construction costs had reached £20,000, but the tolls were meagre, averaging just £236 per year between 1793 and 1796. The navigation was in the hands of a receiver from 1797, but by 1805, enough funds had been raised to open another 1.5 miles (2.4 km) to Freshfield Bridge. Tolls increased sufficiently for the Proprietors to obtain another act of Parliament, the

The works was constructed in two stages, in 1962 and 1977 and can deliver up to 75 Megalitres per day (Mld) for public consumption. Just north of this on the west bank of the river is the Anchor Inn, dating from 1790, which has boats for hire, restaurants and bars, and is licensed for civil weddings. 624: 1584: 1416: 2603:

Valley Way is a long-distance footpath which follows the course of the river. It begins near its source at Horsham, and is 42 miles (68 km) long, ending at the sea near Seaford. The Sussex Ouse Restoration Trust was formed in 2001, with the long-term aim of seeing navigation restored to the upper river, and have completed work on restoring Isfield Lock. However, the Ouse and Adur Rivers Trust see this aim as a threat to the ecology of the river.

After Cliffe the Winterbourne stream flows into the Ouse and also supplies water to the Railway Land nature reserve, owned by Lewes District Council, and managed with help from the Railway Land Wildlife Trust. It covers 25 acres (10 ha) and was the site of railway sidings until 1989. It includes a reed bed called the

The creditors who had installed a receiver were given bonds, and control of the navigation passed back to the Proprietors, who collected £751 in tolls during 1809. By the end of the year, the navigation had been extended to Lindfield Mill. 1613: 1367: 1162: 1139: 1096: 1070: 1020: 1486: 1258: 1000: 941: 839: 457: 384: 2570:(IDB). The Commissioners of the Lewes and Laughton Levels effectively became an IDB until a new structure could be created. This happened in 1939, but rather than creating an independent IDB, flood management of the Ouse became the responsibility of the River Ouse Catchment Board (internal drainage). During the successive reorganisations of the water industry, responsibility passed to the East Sussex 1341: 510: 1656: 1606: 1554: 1508: 1460: 1389: 1308: 1278: 1205: 1182: 1116: 1047: 970: 915: 889: 866: 791: 761: 738: 715: 692: 669: 646: 601: 578: 555: 532: 503: 480: 344: 1636: 1534: 1285: 1251: 1027: 784: 437: 411: 1438: 993: 364: 2590:

Subsequently, The River Ouse (Sussex) Internal Drainage District Order 2016 was passed by Parliament on 18 July 2016, which abolished the River Ouse Internal Drainage District as from 31 March 2017, without creating a formal body to replace it.

In the warmer interglacials the lower valley would have flooded; there are raised beaches 40 metres (Goodwood-Slindon) and 8 metres (Brighton-Norton) above present sea level. The offshore topography indicates that the current coastline was also the coastline before the final deglaciation, and therefore the mouth of the Ouse has long been at its present latitude. 2586:, and when the Environment Agency replaced that organisation in 1995, they managed the River Ouse Internal Drainage District (IDD), together with five other IDDs in Sussex. In 2012, the Environment Agency decided that these functions would be better served by locally accountable organisations, and consulted local authorities as to how best this could be achieved. 2986: 2334:, with a branch to Shortbridge. The Company of Proprietors of the River Ouse Navigation was created by the act, and they had powers to raise £25,000, by issuing £100 shares. Work on the river could not start until the proprietors had raised £10,000, and tolls could not be charged until some work had been done. On 6 June 1791 a second act of Parliament, the 2346:. c. 76) was obtained, covering the work between Lewes and Newhaven, for the purposes of improving navigation and also improving the drainage of the low-lying lands of the Lewes and Laughton Levels. The work was to be jointly supervised by some Trustees and the Commissioners of the Levels, who could then collect tolls for use of their part of the river. 2123: 1995:

Subsequently, he had quarrelled with the other proprietors and had sought to obstruct the project. The difficulties endured for several years, but eventually there was reconciliation with the 2935:

Reasons for the quality being less than good include discharges from sewage treatment works, physical modification to the channel, which prevents the free movement of fish, and runoff from agricultural land.

Between 1813 and 1816, a local papermaker called James Pim bought a property called "Sharp's" in Newick, and built a paper mill close to Sharp's Bridge Lock. He was the only occupant of the building, and by the time it was offered for sale in 1853, the details in the sale documents make it clear that

The river has been used as a source of power, with nine mills known to have existed on the main channel, with four more on the Shortbridge Stream, three on the Bevern Stream, and a tide mill at Bishopstone, to the east of Newhaven. The northernmost of the mills on the main channel was Fletching Mill.

Several attempts were made to improve the tidal river below Lewes. In March 1730, the engineer John Reynolds had surveyed the state of the timber pier at Newhaven, and reported to Parliament. An act of Parliament was obtained in 1731, and the Harbour Commissioners employed him to carry out renovation

The new channel was completed by 1539 and drained the Levels so that much of the valley floor could be reclaimed for pasture.

Barcombe Mill was considerably older, as Thomas Erith had a fulling mill in the 16th century. It was used as a corn mill and paper mill prior to the owner becoming bankrupt in 1706.

Trade along the Ouse Navigation consisted mostly of lime, chalk, manure, aggregates and coal. Whilst in 1801 there were 51 barges registered as trading on the river, of which 21 worked on the section above Lewes, the navigation was never a huge commercial success. In 1825 there was a proposal for a
