River Tay
The River Tay emerges from Loch Tay at Kenmore, and flows from there to Perth which, in historical times, was its lowest bridging point. Below Perth the river becomes tidal and enters the Firth of Tay. The largest city on the river, Dundee, lies on the north bank of the Firth. On reaching the North Sea, the River Tay has flowed from west to east across central Scotland.
The Rythe
It runs under the six-lane A3 into wooded Arbrook Common there joined by three further headwaters rising in the suburban area of a suburban village with many amenities, Claygate, immediately to the east (right bank). It carries on north bounding Littleworth Common and Hinchley Wood to the Scilly Isles roundabout at part of remnant wooded Ditton Marsh, today cast as part of Esher, containing Esher railway station to which its roads (two arterial) connect and in Esher post town. It then follows the Portsmouth Road east through part of Thames Ditton proper and alongside the South Western Main Line. It receives its shorter east branch (rising in Surbiton Golf Course, Long Ditton within Elmbridge) then turns running into the Thames near Ferry Road, 800 metres north.
