The source is somewhere near the town of Fleet, and the river that flows out from Fleet Pond is marked as Fleet Brook by the Ordnance Survey. The streams that flow into Fleet Pond are largely un-named, on modern and historic maps, but are treated as part of Fleet Brook by the Environment Agency, for the purposes of monitoring water quality.

Reservoirs near Parkhurst Hill are №s 1-5 to exclude non-existent 4, south-east of Fleet. Their water treatment is north of №2. The Environment Agency measure water quality from downstream of the intake. The stream wends north, passing under Bourley Road, and is joined by another, which rises from a spring to the west. The stream is briefly called Gelvert Stream as it passes under Aldershot Road marshy terrain, Gelvert Bottom. Another stream and surface water drains join before it is crossed by the A323 Norris Hill Road and passes under the Basingstoke Canal. Others join before it dissipates into marsh on the south-eastern edge of Fleet Pond.[1]

A second stream begins on Greendane Copse, a little to the north-west of the reservoirs. It is culverted under a sports ground, and then reappears until it reaches Aldershot Road, beyond which it crosses housing estates in Church Crookham and Fleet, largely in culvert, but with short open sections. In Oakley Park, it is exposed again, and has an inflowing stream, an overflow on the Basingstoke Canal, and passes under the A323 road and Albany Road to reach the north end of the park. Three more bridges carry the B3010 Kings Road, Southby Drive, and Avondale Road over the watercourse, and it flows into the south-west corner of Fleet Pond.

A third stream begins in the Forest of Eversley near a five-sided enclosure, the ex-Church Crookham Military sewage works,[2] licensed to discharge at most 1.56 Ml per day in the early 1990s.[3] The stream passes by Fleet Infants School, designed by Michael Hopkins and Partners replacing the Victorian school, under the canal and through housing estates, remaining on the surface until it reaches Brooklyn Gardens, beneath which it is culverted to reach Fleet Pond.[1] The school is statutorily recognised and protected as grade II listed. The teachers and the architect saw that the boggy heath, south not be drained for playing fields, but kept as a biodiverse habitat enhancing learning.[4]

Fleet Pond is part of a nature reserve, and covers around half of the 141-acre (57 ha) of the designated Site of Special Scientific Interest.

A weir maintains the level of it. The river exits over it, passes under the A3013 Cove Road, and runs parallel to Minley Road. It then crosses under the road and heads north-west through Broomhurst Wood, under the M3 motorway and is joined by Minley Brook on its right bank.[1] Formerly, this section was less important, and the main river continued northwards from before the Minley Road Bridge. Fleet millpond and Mill were located just to the north of the bridge,[5] but an office block has been built on the site. Beyond Ancells Road, the original course is still in water, passing under Barley Way and the M3 motorway and then weaving between buildings at Brook House, to join Minley Brook. It is now marked as a drain on maps. Minley Brook rises a little further to the east as a series of drains and springs in marshy ground.[1] Brook House is not a listed structure, but predates the town of Fleet by at least 50 years, and possibly considerably more. It appeared as Brook Farm on maps from 1806, when it was already well-established.[6] The remains of a brick-lined moat are located close to the house, and this is a locally listed asset because of its archaeological interest.[7] The stable block and clock tower contain a clock manufactured by John Moore & Son of Clerkenwell in 1830, and repaired by Smith & Sons, also of Clerkenwell, in 1921.[8]

Beyond the junction with Minley Brook, the main river continues westwards, taking treated sewage from the Fleet works on its left bank. In 1991 it was licensed to discharge at most 23.7 Ml per day into the river.[3] A little further downstream from the works, the river passes under Pale Lane Bridge. After meandering across partially wooded countryside, it is crossed by Home Farm Lane, and briefly enters Elvetham Park, the grounds of Elvetham Hall, where it joins the Hart on the park's north limit near Hartley Wintney.[1]

Milling

There is clear evidence for at least one water mill on the Fleet Brook. Isaac Taylor's map of Hampshire, produced in 1759, names Fleet Mill, Fleet Pond and Fleet Farm, and it was marked as a corn mill in 1872.[9] It continued in use until around 1940, and in 1990, English Heritage inspected it to see whether it should become a listed building, but decided that it did not have sufficient merit. The site is now occupied by office buildings, although a small part of the mill has been incorporated into the design.[10]

Water quality

The Environment Agency measure 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. Components used to determine this include biological status, which looks at the quantity and varieties of invertebrates, angiosperms and fish, and chemical status, which compares the concentrations of various chemicals against known safe concentrations. Chemical status is rated good or fail.[11]

The water quality of the Fleet Brook was, in 2019:

Section Ecological Status Chemical Status Overall Status Length Catchment Channel
Fleet Brook[12] Moderate Fail Moderate 10.0 miles (16.1 km) 12.77 square miles (33.1 km2) heavily modified

Reasons for the quality being such include: discharge from sewage treatment works; runoff from agricultural land; physical barriers such as weirs and impounding of the water which prevent the free migration of fish and other species; runoff from roads; and leaching from landfill sites.
