The Hurley Lock is a lock on the River Thames in England . It is located near some islands near Hurley in Berkshire . The lock was built in 1773 by the Thames Navigation Commission .
There are several weirs between the islands, the main one being on the island furthest upstream and connecting to the Buckinghamshire shore . It is often used with kayaks .
history
There was a floodgate at this point, known as the New Lock in the 16th and 17th centuries . It is one of the first to be built after the reorganization of shipping on the Thames after 1770. Like the other locks at that time, it was first built from spruce , which was then replaced by oak . The lock was repaired in 1780 and 1785. During the second repair, the owner of the lock was instructed to keep it operational. Further repairs were carried out in 1791 and 1910, and it was still made of wood. Then it was rebuilt in stone.
The wooden winch that was used to pull boats through the lock looks like a capstan and can still be seen at the lock today.
The river above the lock
The Frog Mill Ait and the Black Boy Iceland are on a sharp bend in the river. The Magpie Iceland is before near Culham Court Hambleden and Hambleden Lock achieved.
The Thames Path stays on the Berkshire waterfront and makes a detour via Aston before returning to the river where it runs to Hambleden Lock.
Use with kayaks
The Hurley Lock Weir is a playboating center as the waves are the right size and shape. When open, the gates create a standing wave .
The gates of the weir
The four gates of the weir are opened and closed to control the water level in the river. Their open state determines the usefulness and difficulty of the conditions.
- Gate 1 - A medium sized ripple normally on the right side of the river. Best for long fast boats.
- Gate 2 - A big shaft with a big hole.
- Gate 3 - When gate 3 is open, there are classic wave conditions on the left side of the river. A large central shaft with holes on either side. The gate is usually not open for long and there can be long waiting times for use.
- Gate 4 - A powerful group of interconnected holes.
Water level
Usually more rainfall means more gates open, but this also depends on the weirs in the upper course of the river and is difficult to predict.
A good wave usually forms in late fall, winter, and early spring. The weir is also suitable for driving in summer, but then only for a short time. In winter about 10 mm can be enough to open a gate, in summer it is about 15 mm. Persistent rain is necessary to maintain the water level, as the groundwater level is otherwise low.
