Sandown is a seaside resort town and civil parish on the south-east coast of the Isle of Wight, England. The neighbouring resort of Shanklin and the settlement of Lake are sited just to the south of the town. Sandown has a population of 7,125 according to the 2021 census, and the three Sandown Bay settlements form a built-up area of more than 20,000 inhabitants. Sandown is the bay's northernmost town, with its easily accessible, sandy beaches running continuously from the cliffs below Battery Gardens in the south to Yaverland in the north.
The nearest watercourse on the river map is the River Yar, about 90 m from the middle of Sandown's gauges. It flows on to the sea.
A gauge downstream shows water that has already passed this point; one upstream sees it first. Distances along the river are from the point on the River Yar nearest the middle of Sandown's gauges. From Ordnance Survey’s river map (OS Open Rivers), which leaves out small streams, ditches and culverts, so a nearer one may exist. This describes where water goes on the map; it says nothing about flooding at any address. Contains OS data © Crown copyright and database rights 2026.
