This lock took its name from the nearby dry dock in the Stroudwater Company's maintenance yard. (For sources, see end of page.)
Completed in 1778, this is the second in a flight of five locks that carried the Stroudwater Canal up the hill past the village of Eastington. It was originally known as Court Orchard Lock after the field in which it was built. The name changed after a covered dry dock was built alongside in 1821 (in centre of picture).
After the canal was closed in 1954, the lock gates were replaced by a concrete dam to maintain water levels suitable for anglers. Later much of the debris from the demolition of Pike Bridge was dumped into the lock, making life very difficult for the volunteers restoring the lock in the early 1990s.
The Company's maintenance yard developed on what was known as the Island (as it was almost surrounded by the waters of the canal and the Oldbury Brook). As well as the dry dock near the lock, there was a carpenter's shop, a blacksmith's forge and a saw pit. The adjoining Dock House was occupied by the man in charge of the yard. The carpenters shop and Dock House have survived.
At the western tip of the 'Island' was a boat house where the Company's ice boat was kept when not in use. To the east of Dock House was a spill weir from the pound above the lock, and a channel carried any surplus water from that pound into the Oldbury Brook. This channel survives, but it will be replaced by a new structure built on the towpath side
Sometimes called Canal House, the house adjoining the maintenance yard was built in 1807 for the man in charge of the maintenance team. In the early days, the occupant was usually described as a surveyor, carpenter or foreman. From 1892, however, as Company finances were under growing pressure, the house was made available to whoever would pay the rent. After the canal closed, the house was sold to a private owner in 1956.
For lock completion date, work was still 'in progress' in Jan 1778 - D1180/1/1 p183.
