The catchment area of the Medway covers almost 25% of the county. The detailed map has a diagram of that catchment area, which includes its main tributaries: the rivers Eden, Bourne (or Shode), Teise, Beult, Loose and Len.
The River Teise (pronounced tice or teeze) begins in Dunorlan Park in Tunbridge Wells[1] and flows eastwards through Lamberhurst, passing Bayham Abbey. Here the small River Bewl, on which is the reservoir Bewl Water, joins the Teise. The Teise bifurcates 2 km SW of Marden, the minor stream flows directly to Twyford Bridge, Yalding, while the major stream joins the River Beult at Hunton, 1.5 km above Yalding.
The River Beult (pronounced belt) has its several sources west of Ashford, and then flows through Headcorn and where it is joined by the major stream of the Teise. The river enters the Medway at Yalding.
The River Loose is a relatively short river starting near Langley south east of Maidstone running west through Loose and joining the Medway at Tovil.
The River Len has its source at a small watershed south of Lenham. A nearby stream is one of the sources of the Great Stour. The Len flows in a westerly direction and joins the Medway at Maidstone.
The River Stour is also known as the Great Stour, especially above its confluence with the Little Stour at Plucks Gutter. Its catchment area covers the eastern part of Kent.
