Woodhead Reservoir gets its name from the mayor who laid the foundation stone on the first of May 1897, Sir John Woodhead J.P.
The summit plateau of Table Mountain, with an average rainfall of 1600mm, is an ideal water catchment, and the Back Table contains five reservoirs including this one. The others being Hely-Hutchinson, Victoria, Alexandra and De Villiers. The five reservoirs have a combined capacity of 2273m litres. For a long time these were the city's main sources of water. Some of the water is carried down Table Mountain by means of two tunnels, the Woodhead and Apostles tunnels, 1313 metres in length through Wood Buttress, to a filtration plant above Kloof Nek.
During the same period, the last decade of the 19th century, saw the establishment of the Tokai plantations and the commencement of tree-planting on a large scale on Table Mountain and Devil's Peak.
At the time of completion the Woodhead and Hely-Hutchinson reservoirs were considered engineering triumphs.

INTERNATIONAL HISTORIC CIVIL ENGINEERING LANDMARK
BUILT BETWEEN 1893 AND 1897, THE WOODHEAD DAM WAS THE FIRST LARGE
MASONRY DAM IN SOUTH AFRICA. A REGIONAL WATER SYSTEM WITH A MAJOR
RESERVOIR WAS A BOLD VENTURE REQUIRING DIFFICULT CONSTRUCTION IN A
REMOTE AREA. INNOVATIVE TECHNIQUES, INCLUDING AN AERIAL CABLEWAY TO
CARRY MATERIALS, WERE NEEDED. THE DAM'S SUCCESSFUL COMPLETION PAVED THE
WAY FOR SISTER DAMS THAT CONTINUE TO SUPPLY WATER TO CAPE TOWN AND
ENVIRONS AND ESTABLISHED YOUNG THOMAS STEWART, THE ENGINEER WHO
DESIGNED AND MANAGED THE PROJECT, AS A LEADING WATER ENGINEER AND
RELIABLE CONSULTANT. STEWART IS KNOWN AS THE FATHER OF CONSULTING
ENGINEERING IN SOUTH AFRICA.
