Penton Hook Island is a mainly wooded former peninsular created into a series of three weir-divided islands in the River Thames in England in river modifications since 1815. It has the lock and weirs that are the divide between the Laleham Reach, above Chertsey Lock and Staines Reach, above Penton Hook Lock. ==Geographical features== At this point the natural course of the river forms naturally almost a complete loop, a hook shape of a peninsula which is attached to the towpath (here, northerly) bank in the form of walk-over, relatively wide, lock gates. The long hook or spit of land forms today a series of three weir-divided islands in the River Thames in England, adjacent to Penton Hook Lock. It has been since at least the medieval period the southern extremity of Staines upon Thames. Across the river is neighbours Penton Hook Marina, Penton Hook Yacht Club and riverside homes of Thorpe, Surrey, to the west and riverside homes of Laleham Reach, Chertsey to the south and east, the latter being the most distant part of Chertsey from the town itself. In administrative geography the area forms the southern extremity of the ancient (and current as of 2015) ecclesiastical parish of Staines.〔(Parish Finder - clicking slightly to the east to avoid Egham Hythe ) The Church of England.

It is more robustly protected from initiatives to construct on green field sites by being part of the Metropolitan Green Belt settled national planning policy.〔('Staines: Introduction' ) A History of the County of Middlesex: Volume 3, ed. Susan Reynolds (London, 1962), pp. 13-18〕 The three sluice-controlled barrages allow control of the river at its highest by the construction of the large weir at the apex of the long loop and further weirs along the narrow north section.〔(Penton Hook - River Level on weir-side measure over 48 hours ) Environment Agency. Accessed 2015-04-15〕 The uninhabited island in public ownership is fairly wooded and is used for nature conservation and appreciation. The west has a backwater dug out to provide a fish refuge when the stream is strong and a fish spawning stream constructed in 1999. The island has many paths laid out for viewing its trees, squirrels, nesting birds, fish and waterfowl. These particularly cater for angling; for the Thames two permits are issued by the Environment Agency that can be bought online or in post offices. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Penton Hook Island」の詳細全文を読む スポンサード リンク
