The Masonry Dam under construction, c.1897. Looking upstream. Note the rake line and Black Bridge at very top of picture. An incline was built from the rake, allowing materials to be brought to the site, and facilitating their placement. A coffer dam of sand bags was constructed (centre and centre right) to allow the placement of foundations on the stream bed. Two hand operated cranes were in use. HP Barry Collection photo, WACMA.
Detail from previous image. At least twenty five men are working at the site. The man second from left is operating an endless bucket lift to pump water from the inside of the coffer dam.
Another view of the early construction of the Masonry Dam, showing the inside of the coffer dam, where the workmen are placing the foundations of the dam. Note the cut out in the opposite bank. Photographed from the southern or true left bank, ie river flowing right to left. Circa 1897. HP Barry Collection photo, WACMA.
The partly completed Masonry Dam. The coffer dam is flooded. Note the small tunnel where the dam wall meets the dam wing. This is the drainage outlet. Circa 1897. HP Barry Collection photo, WACMA.
Working on the northern bank of the Ohinemuri River. Circa 1897. HP Barry Collection photo, WACMA.
The completed Masonry Dam. Water is overflowing the dam (it frequently didn’t), hence the drainage outlet tunnel is obscured. The water race inlet structure is behind the dam wing at extreme right. The inclines have been removed. Circa 1897. HP Barry Collection photo, WACMA.

Inlet structure of WGMCo.s Victoria Battery low level water race in fore ground (dam not visible to left), Black Bridge on the rake line top right.
The Victoria Battery low level water race upstream water race flume bridge crossing the Ohinemuri River. We are looking downstream. HP Barry Collection photo, WACMA.
The Victoria Battery low level water race downstream water race flume bridge crossing the Ohinemuri River under construction. We are looking downstream. The three centre trestles are temporary. HP Barry Collection photo, WACMA.
The Victoria Battery low level water race downstream water race flume bridge crossing the Ohinemuri River completed. We are looking downstream. The tramline passed underneath the left most end of this bridge (not visible in the photograph). HP Barry Collection photo, WACMA.
The Victoria Battery low level water race upstream end of the "Siphon". The water entered this pipe where the sand bags dam the water race, top left of this picture. The sand bags were ultimately replaced by a concrete structure. Circa 1897. HP Barry Collection photo, WACMA.
The Victoria Battery low level water race downstream end of the "Siphon". The water exited this pipe centre foreground, and became an open ditch once again. Circa 1897. HP Barry Collection photo, WACMA.
The Victoria Battery low level water race ultimately delivered water to two 200HP turbines, one of which is shown here. The turbine drove the stampers via the rope drive wheel at the right of the photograph. Auckland Weekly News 1898.
Old map of the Victoria Battery. Date unknown, but after the electrification of the plant in 1913.
The water race is shown entering the site. The straight section in front of the Transformer House still holds water today. Note the penstock, and the low pressure pipe 54" which also remain (at the left hand end of the water race). The turbines were situated on the river side of the first 100 stamps, at the head of the tailrace shown on this map. Note further the high pressure pipe, crossing the bridge at top left, bringing water from the High Level Water Race (Waitekauri). WACMA.
