Penton Hook Island

Penton Hook Island is a mainly wooded former peninsula created into a series of three weir-divided islands in the River Thames in England, so created in river modifications since 1815 with a navigable lock and weir stream channel to form meander cutoffs. It has a lock and weirs that are the divide between the Laleham Reach, above Chertsey Lock and Staines Reach, above Penton Hook Lock.

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 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 it neighbours Penton Hook Marina, Penton Hook Yacht Club and riverside homes of Thorpe, Surrey to the west and similar homes along Laleham Reach, Chertsey to the south and east, the latter being the most distant part of Chertsey from the town itself.
