Ardgowan - the last 100 metres

Selected for Google Maps and Google Earth

The last section of the race on easement lands. After this the race flows through a tunnel (tunnel #5) and out into the reservoir which is itself on a large Waterworks Reserve.

The race is formed from rectangular section poured in place concrete here and it incorporates three gates - being a bywash and two stop-log gates with a screen to trap sticks and other filterable detritus with a discharge into Mill Creek. It is a shame that it is being used as a trash dump!

Looking upstream from Ardgowan road onto the last section of the race before it enters the reservoir reserve. The tunnel entrance is in the blackberries at the right edge of the picture and the concrete diversion system is in the middle of the frame.

Some idea of the extent of the easement (land acquired by the Borough Council on which to locate the Borough Race) can be gained in this picture. The black hut is modern.

Note also the extent of the concrete works for this important facility. Before the water was even filtered before being sent into Oamaru through the reticulation system, let alone treated! the control of water quality depended very much on the vigilance and work of the Reservoir Raceman at this diversion.

As an aside, the diversion of water into Mill Creek would have been of benefit to the operators of The Phoenix Mill (see photo No.57210209)
