Description

Gloucester Lock is a lock that connects the Main Basin of the Docks with the River Severn. It was completed in 1799 as a two-chamber lock in a staircase design, created by architect and engineer Robert Mylne and resident engineer James Dadford for the Canal Company. In 1892, it was remodeled into a single chamber for the company and the River Severn Commission. The lock features a concrete-lined basin with ashlar coping on both sides. At each end, there are timber double gates that carry footbridges. Originally, these gates were operated by timber balance beams reinforced with iron girders, but they were later equipped with hydraulic paddle gear. Additionally, separate flood gates are fitted at the north end of the lock.

Local climate

Gloucester Lock receives an average of 770 mm of rain a year. This makes it drier than 62% of listed buildings in the UK. Its exposure to wind-driven rain is lower than that of 53% of listed buildings.

It experiences an average of 37 freeze-thaw cycles a year, more than 66% of listed buildings. Of these, 17 follow at least 1 mm of rain in the preceding 48 hours. Average temperatures at this location have risen by 0.3°C per decade since 1991.

Averages for 1991–2020; temperature trend 1991–2025. Figures describe the wider area (a grid cell of roughly 10 km), not the individual site. Contains modified Copernicus Climate Change Service information 2026.
