River Hart

The River Hart

The River Hart is a tributary of the River Whitewater in northern Hampshire. It rises at Ashley Head spring in Crondall (51°14’7"N, -0°51’33"W) and flows north to meet the Whitewater at Bramshill (51°20’32"N, -0°56’13"W).

Course

The Hart rises at a series of springs on Crondall golf course. From the main spring at Ashley Head, it flows northwards, hemmed in by housing, and is crossed by Redlands Lane, before passing under the drive of East Bridge House, an early 19th-century mansion with older core, which is a Grade II listed building.

The river passes Marsh Farm Business Centre (on its right bank), then fields, then passes under the Basingstoke Canal near Crookham Wharf. After running along the backs of housing on Crondall Road, it passes under the road, to be joined by a stream on its left bank which has come from springs and ponds known as 'Itchel Mill Springs'.

Below this point is Pilcot Mill at Dogmersfield, a two-storey millhouse from the 18th century, last used for milling in 1928. Its mill cottage has 17th and 18th century elements. On the downstream side of Pilcot Bridge is a large timber-framed house of about the same date, known as Catherine of Aragon (House).

Pilcot farm is on the left bank, and then the river passes often tree-lined through fields west of Fleet, where ditches add to it. The channel splits into two to pass under the South West ain Line embankment, fields being drained up to about the M3 motorway. A key ditch begins across the latter, and runs beside the main channel on its left bank. Both are crossed by the A323 Fleet Road, and are controlled by sluices as they enter Elvetham Park.

The park was created in the 14th century. It was re-landscaped in 1591 for Edward Seymour, 1st Earl of Hertford to entertain Queen Elizabeth I with four days of lavish festivities. Courtiers were offered a booklet describing the entertainment. In the 18th and early 19th centuries the park was extended and planting took place in some areas, while ornamental and formal gardens were added in the later 19th and early 20th centuries. The original Elvetham House burnt down in 1840, and was replaced by the grade II* listed Elvetham Hall built between 1859 and 1862 by Samuel Sanders Teulon. Additions were made to the building in 1901 and 1911–12, while the grounds include a Norman-style church building erected in 1840 by Henry Roberts.

The river runs through the park, separating Elvetham Park to the south-east from New Park, to the north-west. A lake was constructed in 1871, to the north-east of the hall, but this had become overgrown with vegetation by the 1980s, and a weir and bypass channel were built, so that the river could be diverted around it to allow it to be dredged. Teulon also built a bridge over the river, with two segmental brick arches and wrought iron gates.

As the river leaves, it is joined by the Fleet Brook on its right bank. Hartford Bridge carries the A30 road over the river at the small village of Hartfordbridge. Shortly afterwards, Hartley Wintney sewage works outfall is received. The Hart continues through wooded countryside, and enters Bramshill Park. Its original 2,500 acres of land was enclosed by Thomas Foxley in 1347 as a deer park, and he later built the house. Edward, Lord Zouche of Harringworth, a diplomat, bought the estate in 1605, and built a mansion between 1605 and 1612, incorporating part of the house. The park was landscaped in the 17th century, and in the late 18th and early 19th centuries, the river widened to form the Broad Water. The estate was sold in 1952, and parts of it became a Police Training College. The site was given a grade I, top, listing, having an early 17th-century water garden. Its associated mansion is one of three Jacobean buildings known to include two state apartments, one for the king and another for the queen. Within the park is a grade I listed bridge crossing the river, built in the early 19th century in Jacobean style, with two red-brick arches and stone dressing. After leaving the park, the river is crossed by Plough Lane at Lea Bridge, and then joins the River Whitewater, on its right bank.

Milling

There is clear evidence for two water mills on the Hart, both of which were corn mills in 1871. Only Pilcot Mill at Dogmersfield survives. It is a small building with three storeys, constructed with a timber frame and brick infill. A mill in Dogmersfield was mentioned in the Domesday Book, compiled in 1086, but it was probably a little further downstream at a building known as Pilcot and more recently, Catherine of Aragon. There are records for a mill at there from the 15th, 16th and 17th centuries. The surviving mill dates from the 18th century, and the last record of it being used dates from 1928. In the 1980s, Anne and Geoff Finnigan owned the mill, and by the late 1980s, a considerable amount of restoration had been carried out. The mill was powered by an external Poncelet wheel, a more efficient form of undershot water wheel, but its condition in 2013 was poor. Internally, all of the machinery and two pairs of stones are still in situ. There is evidence that water power was supplemented by an engine, the base for which can still be seen. Because the river was prone to flooding, there are two bypass channels running parallel to the wheel pit.

There have also been mills at Crondall, below Itchel Mill Springs. There was a mill there in 1068, when it was valued at three shillings (15p), but by 1327 it was described as "an utter ruin and of no value". Two water mills were mentioned in 1653, and three grist mills under a single roof in 1773. The final mill building was erected some time before 1850, and was demolished in 1945. The adjacent mill house has been replaced by a modern residence. The mill was always seasonal, as the mill pond was fed by a spring, which was dry for part of the year. Generally, the pond filled in February each year, and milling could take place for several months afterwards.
