Dobbs Weir Lock

Dobbs Weir Lock is a navigation lock on the River Lea in Hertfordshire that allows boats to move between different water levels. The lock measures approximately 26 meters long and 5 meters wide, with a water level difference of about 2.4 meters between its upper and lower gates.

The lock was built in the 18th century as part of the River Lee Navigation system to support the movement of goods between London and rural regions. It remains a functional piece of this historical waterway that once drove commerce and connection across the river valley.

The lock sits along the Lea Valley Walk, where people come to walk, cycle, and fish in the river. It serves as a meeting point for those enjoying outdoor activities in the valley.

The lock is maintained by the Canal & River Trust and is accessible to boaters navigating the river. Visitors should plan to spend time at the lock as it takes several minutes to pass through, and guidance is available from staff on site.

The lock creates a habitat that attracts numerous water birds and aquatic species, making it a quiet spot for wildlife observation. Many visitors are surprised to discover that they can watch herons, ducks, and other river animals while passing through.
