Hardmead Lock (No3) is a lock on the River Lee Navigation at Great Amwell close to the town of Ware.

The lock has a reputation as being difficult to negotiate. [1]


The lock-keeper's cottage stands on an island formed by a section of the River Lee Flood Relief Channel which flows through an automatic sluice gate adjacent to the lock. [2]

To the east of the lock is the Amwell Quarry nature reserve a Site of Special Scientific Interest (SSSI) [3] and a section of the Old River Lea known as the Amwell Magna Fishery where it merges with its tributary the River Ash .

The New River flows close by to the west.

Public access[edit]

The lock is located on the River Lee Navigation towpath which is part of the Lea Valley Walk
