Oldbury Brook and Spill Weir

The Oldbury Brook crossed the canal and flowed over a spill weir on its way to join the River Frome. (For sources, see end of page.)

Oldbury Brook

Throughout the working life of the canal, the Oldbury Brook flowed into the canal to the east of Westfield lock, and most of that water continued over a large spill weir/sluice on its way to join the River Frome.

The brook was also known as the Back Brook as it gave access to the back of the Company's maintenance yard for the delivery of materials. The Back Brook became a convenient place for vessels to moor while waiting their turn to go into the dry dock or while additional repairs were completed after a visit. Unfortunately, it also became a place where vessels were abandoned, and several owners had to be threatened with penalties because their vessels were causing an obstruction or had actually sunk.

The weir has a long crest to cope with a variable flow without much change in the level of the pound. The structure includes a sluice to lower the pound for maintenance and a low level culvert to drain the pound if needed.

In the late 1980s and early 1990s, volunteers removed silt and debris that had accumulated in the structure and they repaired the stonework. They also formed an earth dam across the pound to divert the Oldbury Brook into a new channel provided at the time the M5 motorway was constructed - so the sluice under the spill weir structure now only has to take the water coming down the locks. For the current restoration project, it is planned  to build a culvert to carry the Oldbury Brook under the restored canal.

Coal Pen

Immediately east of the spill weir was a wharf with a coal pen for the temporary storage of coal destined for nearby Meadow Mill or one of the other village mills. The site is currenly obscured by an overgrown mound. During a trade depression in 1843, local mill owner Charles Hooper arranged for 200 tons of stone to be landed here. Those out of work were thus able to earn some money breaking the stone for the roads, and there were no disturbances in Eastington like those recorded elsewhere at that time.

The Back Brook also gave vessels access to a wharf serving the district workhouse, built in the 1830s to serve a group of local parishes. Barges delivered stone to be broken up by the inhabitants for use on local roads.

In 1882, the Stroudwater manager expressed great concern when he found that a new drain into the canal came from a building that was being prepared for smallpox patients. Furthermore, part of the Back Brook had been taken up for confining ducks, and he threatened to run a boat into the structure to knock it down.
