Description

Denver Sluice is a sluice and bridge built in 1834 by Sir John Rennie. It was enlarged in 1923, with a new flood gate added in 1928. The gates were replaced in 1960 and again in 1983. The structure is made of brick, stone, and steel, featuring a four-arched bridge of brick that is finished with ashlar and rusticated details. There are four ashlar piers, with the outer two projecting to the north and south to form locks. The sluice has three chambers that are controlled by timber tide gates to the north and three steel guillotine gates to the south.

Local climate

Denver Sluice sits in one of the driest parts of the UK, with an average of 700 mm of rain a year. This makes it drier than 91% of listed buildings in the UK. Its exposure to wind-driven rain is lower than that of 93% of listed buildings.

It experiences an average of 30 freeze-thaw cycles a year, fewer than 64% of listed buildings. Of these, 15 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.
