The Teise bifurcates 1+1⁄4 miles (2.0 km) south west of the village of Marden, passing either side of a low ridge.

The Lesser Teise flows for about 4 miles (6.4 km) before joining the River Beult at Hunton.

The Greater Teise, now carrying only minor quantities, flows for about 5 miles (8.0 km) to the River Medway at Twyford Bridge, upstream of Yalding, formerly the site of a double ford over both the Medway and Teise rivers.

The Beult flows through Yalding, then also joins the Medway about 6 furlongs (1.2 km) below Twyford Bridge.

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.

There are several components that are used to determine this, including biological status, which looks at the quantity and varieties of invertebrates, angiosperms and fish.

A painting of the mill by Charles Tattershall Dodd (1815–78) can be seen in Tunbridge Wells Museum & Art Gallery.

The furnace produced 200 tons of iron in 1717 and John Legas was working it in partnership with William Harrison.

William Collins and George Matthews leased the furnace in 1782 but it ceased production c.1787.

This was a corn mill; the building survives today converted to a dwelling, devoid of machinery except the sack hoist.

[13] Only the cast iron hub of this wheel remains, on a wooden axle of some 18 inches (460 mm)diameter.

Owners include George Culvin in 1716, Thomas West in 1725 and Edward Blackwell in the 1730s and 1740s.

It was a small timber-framed building of three storeys, clad in white painted weatherboarding.

William Jr was followed by his son Henry, who died in 1892 and the mill then ceased working.

The Arnold family were millers here before taking Branbridges Mill, East Peckham in 1890.

A modified furnace continued in use at Bedgebury for some time for the firing of clay and bricks, produced by the various workshops at Cranbrook Pottery; however the advent of production in the Midlands with better availability of power, transport, labour and materials all but ended hopes of retaining industry in the area.

The original bloomery or hammer pond has now silted up but remains as a distinct flat flood plain which clearly defines the approximately 20 acres (8.1 ha) that originally held the water reservoir.

The sluice has long been dismantled, however the race is clearly visible to walkers using the bridleway that crosses the river Teise on a stone bridge.

An old site, the Furnace Pond remains today, having an area of some 30 acres (12 ha).

In 1588 the furnace was leased by William Ashburnham and sub-leased to Thomas Johnson, a gun-founder.

In 1596 the furnace was owned by Sir Thomas Waller, and leased to John Iden and Robert Pothill.
