The Mill was next to the lock, where a sluice gate now stands. The mill was demolished in the first half of the 20th century.
Harlow Mill Lock was one of only two brick-sided lock chambers built when the Navigation was canalised between 1766 and 1769. The chamber was too deep and the mill too close to build safely a turf-sided lock.
The timber-framed lock house was built in 1803 but was replaced by British Waterways in the 1960’s.
The date and composition of this postcard suggest that this is possibly Henry Clayden and Frederick Ward standing outside the house on or soon after 31.3.1901. See the census record below.
13.7.1912 "The lower gates of this lock collapsed...the offside gate is in the bottom of the lock and the other one is completely shattered and is now pointing the reverse way. I am glad to say that no-one was hurt, the lock was being filled at the time...I am preparing plans for new gates with a deeper sill to give us increased depth of water" C Tween (LMA/ACC 2423/012)

This photograph shows the lock shortly after rebuilding following the collapse (compare the lockside in the two images above). The lock keeper here is Joseph Salmon, appointed in 1911.
This is another photograph of him, possibly taken the same day, unless he always left the bottom button of his uniform undone! He is accompanied in both pictures by his dog Laddie.

In 2008 this sculpture "The Flowing River" by Antony Lycycia was erected on the eastern side of the lock chamber. The words paraphrase the legend on the missing plaque from Latton Lock house.
