made the river navigable up to Midhurst by constructing eight locks and some small cuts. The work was completed in 1794, and many of the bridges built at that time still survive. With the opening of the Mid-Sussex Railway
branch to Midhurst in 1859, traffic declined, and commercial use of the river had ceased by the 1880s. Pleasure boats continued to be used on the river for many years, and published accounts of journeys along the decaying navigation appeared in 1914 and 1920.

which would enable him to improve the Rother. The Act also authorised a branch canal to
Petworth. Since he owned most of the land adjacent to the river, the precise route of the navigation was not specified, and he was free to improve the channel or make cuts as he saw fit. The only restriction was that cuts could not be made through gardens or enclosed grounds. Compared to most other canals at the time, the charges for using the navigation were low, as the Earl wanted to develop the region rather than make a profit.
The river's lower section, below Midhurst, was made navigable by the construction of the ''Western Rother Navigation'' in 1794.
The length of the navigation was of which less than consisted of new cuts, with the rest following the existing channel. It rose through from Stopham to Midhurst by a series of eight locks, and cost £13,300 to build. Traffic consisted of coal transported up-river, with cargoes of timber, corn and Petworth marble in the other direction.
A branch connected it to Petworth by the short

were brought into the neighbourhood to carry out the work, the Earl employed local men on the project, most of them already employed by him, and a clergyman praised him for this when writing in 1808, as it led to much less disruption, but provided increased income for those who worked on the scheme. Wages rose from 8 or 9 shillings (40-45p) per week to 14 or 15 shillings (70-75p). During his life, the Earl invested some £100,000 in waterways, some in his native county of Sussex, but also in attempts to build a canal from London to Portsmouth. Between 1802 and 1831, the average income from the canal was around £550 per year. Competition arrived in 1859, when the Mid-Sussex Railway opened a line from Horsham through Pulborough to Petworth. Traffic declined, and by the 1880s, the navigation was no longer used by commercial boats, although it was not officially abandoned until 1936.
Closure
Despite the navigation being closed, a guide to Midhurst published in 1895 advertised that skiffs could be hired, and fishing could be enjoyed. The boats were hired out by a plumber called William Port, and his business continued to prosper until 1912, when his boathouse burned down. Rowing boats were also available for hire at Coultershaw and Fittleworth. Another book called ''A New Oarsman's Guide'', published in 1896, suggested that the river could be canoed from Iping to the Arun, a distance of , when there was sufficient water. By that time, none of the locks were workable, and boats had to be carried around them.

of Petworth, a successor to the Earl of Egremont, should pay for its repair. After some disagreement, a compromise was reached, under which the bank was repaired and a floodgate was fitted at the upper end of the lock, with both men paying half of the cost. Lord Leconfield assumed that when the Arun Navigation finally obtained an Act of Abandonment in 1896, his responsibilities for the maintenance of the River Rother had ended. However, in 1903 heavy rain and floods destroyed the floodgate and part of the adjacent weir, resulting in river levels though the 8th Earl of Egmont's estate dropping by . The Earl, Augustus Arthur Perceval, issued a writ against Lord Leconfield for damages. The case was heard in the High Court, at which it was agreed that the navigation was now useless, but that the two men would share the costs of rebuilding the floodgate, after which responsibility for its maintenance would pass to the Earl, who could also dredge the river above the lock.
P Bonthron, who published a book entitled ''My Holidays on Inland Waterways'' in 1916, described a journey down the river that he had made with friends in 1908, in a boat hired from William Port at Midhurst. They reached Arundel on the River Arun after two days, from where the boat was sent back to Midhurst by train. Another account of a similar journey made in 1914 by Eleanor Barnes and a friend appeared in ''As the Water Flows'', first published in 1920, which described canoe journeys on the rivers of southern England made by her over a period of seven or eight years. The warrant of abandonment was obtained jointly by the estates at Petworth and Cowdray after an Oxford undergraduate called Roger Sellman pointed out that the river was still officially a right of way, and that anyone could therefore offer to pay the appropriate tolls to use a boat on it, and expect the owners to rebuild the locks. The powers of the Railway & Canal Traffic Act 1888 were invoked to declare that the navigation was no longer necessary, and despite objections from the River Arun Catchment Board and a canoe club, the warrant was granted on 15 April 1936. However, the Environment Agency noted in 2003 that although there used to be navigation rights on the river, "the existing status of the navigation is unknown."

, which consists of clay. At the western edge of the region, both the chalk and the gault turn to the north, creating a scarp slope. The base flow of the river consists of water from the Lower Greensand aquifer, and from springs along the bottom of the chalk scarp slope. These help to maintain the flows in the river during the summer months, although there have been significant periods where flows have been low, notably in the drought of the early 1990s, and again in 1995–96. These led to declines in the populations of the macro-invertebrates which are used to measure the health of a river, but these have subsequently recovered. In order to monitor the hydrology, the Environment Agency has a series of observation boreholes along the valley, and maintains gauging stations at Princes Marsh, close to the source, at Iping Mill, at Halfway Bridge on the River Lod just above its junction with the Rother, and at Hardham, just before the river joins the Arun.

es have been constructed around the gauging stations. The only known population of native white clawed crayfish in Sussex is located in the upper reaches of the Rother.
The quality of the water is generally good, helped by the fact that the groundwater in the chalk aquifer is of very high quality. However, some of the small streams in the upper reaches are polluted by discharges of effluent which are not licensed, and there are areas where the water in the aquifer, and hence the river, has raised levels of nitrates, largely caused by agricultural fertilisers. The Environment Agency has produced improvement plans to address a number of sources of both agricultural and urban pollution.[ Natural flows in the river are affected by the abstraction of water for the public water supply. There are many locations at which water is abstracted along the course of the river, including a site in the upper reaches where more than per day is abstracted from the aquifer, and another where the volume exceeds . Just above the junction with the River Arun, the Hardham Water Treatment Works removes more than per day from the river.

There was a wharf and basin, close to a road which is still called The Wharf, and an ashlar bridge crosses the navigation between the wharf and the junction with the main river. It was built in 1794, and was restored in 1977 to commemorate the silver jubilee of Queen Elizabeth II. The first lock was near Little Topham farm.

It dates from the construction of the navigation, and is virtually unaltered. Nearby, the Petworth Canal headed northwards to Haslingbourne Bridge. Below the end of the cut, the river is joined by the stream from Burton Mill Pond, which supplied an iron forge built in 1789. It is crossed by Shopham Bridge, built in the nineteenth century from red brick with grey headers and a parapet in stone, with three segmental arches. At Lower Fittleworth, there is another mill building, although it is unused and in poor condition. It was built in 1628 and enlarged in 1742. It stands in the grounds of the mill house, which was rebuilt in 1913. The lock cut ran along the south-western edge of the site.][Ordnance Survey, 1:2500 map, 1876] Fittleworth Bridge consists of a southern section, originally built in the sixteenth century, which was rebuilt between 1717 and 1739, and modified when the navigation was built, to enable boats to pass through the centre arch. A north section, adjacent to the millpond, dates from 1811 to 1812.
Near its junction with the River Arun, the river loops to the south in a large meander. A cut ran from the start of the meander to join the Arun above the original junction, with a lock towards the downstream end. The meander fed Hardham Corn Mill. A lock bypassed the mill and the millstream, to enable boats to reach the Hardham Tunnel cut, which headed south from a junction above the mill.[ The Tunnel Branch was destroyed by the construction of a water treatment works, and the modern weir near the mouth is much closer to the junction than the lock was.][

Water quality
The Environment Agency measure the water quality of the river systems in England. Each is given an overall ecological status, which may be one of five levels: high, good, moderate, poor and bad. There are several components that are used to determine this, including biological status, which looks at the quantity and varieties of invertebrate
Invertebrates are a paraphyletic group of animals that neither possess nor develop a vertebral column (commonly known as a ''backbone'' or ''spine''), derived from the notochord. This is a grouping including all animals apart from the chordate ...

The water quality of the River Rother system was as follows in 2019.
The reasons for the quality being less than good include sewage discharge affecting most of the river, some physical modification of the channel, the presence of North American signal crayfish, which are an invasive species, and runoff of chemicals as a result of agriculture and land management. Like many rivers in the UK, the chemical status changed from good to fail in 2019, due to the presence of polybrominated diphenyl ethers (PBDE) and mercury compounds, neither of which had previously been included in the assessment.
