Caversham Lock includes a somewhat larger than normal lock island, separating the lock from the weir. Besides the normal lock_keepers house, this island until recently contained a boat yard and boat house used by the Environment Agency's river patrol and maintenance services. At the time of writing (December 1, 2004), controversial proposals are being discussed to redevelop the island (and some adjoining land) as a hotel.
A public access exists across the lock gates, lock island and weir, forming a pedestrian route from the centre of Reading to the Lower Caversham area of the cross_river suburb of Caversham.
The lock was repaired in 1867 and both the lock and house were rebuilt by the Thames Conservancy in 1905.
The flash lock was rebuilt and enlarged in 1885 but the first pound lock, which was constructed using concrete, was not built until 1928 by the Thames Conservancy despite the fact that in 1817 it was considered that a pound lock was desirable and that it would be built as soon as funds became available.
Although this lock is not on the River Thames (it is on the River Kennet at Reading) it is included here for completeness as this part of the Kennet falls under their jurisdiction of the Environment Agency which owns and operates the lock.
