The island is at the southernmost point of the RiverThames. The garden-lined southern horseshoe curve of the island is mapped as Hamhaugh Point, and being its only tapered side becomes the narrowest width. Otherwise Hamhaugh is almost rectangular: long and wide. It is from the parish churches of Shepperton and Weybridge respectively, however Shepperton High Street is a further north of this whereas Weybridge High Street runs next to its parish church, which means the whole area is closer to Weybridge's urban resources. The town is accessible by boat or a journey using Walton Bridge of more than. The Shepperton Lock area of Old Shepperton has a family gastropub, two marine shops/chandler's shops and the lock's indoor and outdoortea room.
A ferry operates from Shepperton Lock's downstream side to the northern point of Weybridge and links the Thames Path National Trail. A fee of below £1 is payable.
Land use
The island, apart from landings and a patch of woodland with a path running through it along the north side, is residential, consisting of 46 houses and a communal green. Access is on foot or carried bicycle from Shepperton lock, across Lock Island and then across a weir. A second weir, without foot access, connects the island to the right bank: Hamm Point of the Hamm Court residential estate, Addlestone.
History
The island was created and soon thereafter slightly reduced to create a smaller island, Lock Island, to the north, which was also part of the mainland — this creation occurred after the fixing of most non-urban parish boundaries, pre-1700, and explains why given the wide channel dug to its north, it stayed part of the parish of Shepperton. Before the later Thames locks including all those of the mid- to lower Thames were built from 1805 onward, the river here saw flooding across what was a combined island, at various points such as the far north in times of very high tide, when combined with post-rainfall water volumes, this being similar to Penton Hook Island and Desborough Island which were also originally peninsulas. With the additional capacity and cuts along this stretch this acts to bypass the old river when necessary and makes navigation much shorter for river journeys.
