Hurley Lock

Hurley Lock is a lock and weir on the River Thames in England, situated in a clump of wooded islands close to the village of Hurley, Berkshire. The lock was first built by the Thames Navigation Commissioners in 1773.

There are several weirs between the islands but the main weir is upstream between the topmost island and the Buckinghamshire bank. The weir is popular with kayakers whenever conditions are favourable, and it is very busy at weekends.
