Completed in 1872, the reservoir was built by the engineer John Frederick La Trobe Bateman.[2] The first sod was cut on 20 May 1864, by the then Mayor of Halifax, William Holdsworth, who used a silver spade with the inscription:
The reservoir covers 68acres, is 45feet deep when full and holds up to 193000000impgal. It was notably described in Whiteley Turner's 1913 book A Spring-Time Saunter: Round and About Bronte Land.[3]
