Descriptive Note

Gaugings cards are measurements of stream/river flow. The majority of these flow measurements have been undertaken using mechanical current meters. Increasingly flow measurements are undertaken using acoustic Doppler current profilers (ADCP’s). A small proportion of these measurements have been undertaken using other mechanisms such as visual estimates, slope/area, salt dilution, contracted opening, weir and culvert formulas, and a number of less common methods of flow determination.

Gaugings are primarily used to derive rating curves, these describe the relationship between river level and flow. This relationship is the means by which a continuous flow series is derived for a stream or river.

Gauging measurements have been taken by a number of Local and Central Government agencies over the years, they include:

Manawatu-Wanganui Regional Council - Hydrometric Recordings taken by the Manawatu-Wanganui Regional Council with gaugings beyond 9999. Agency Code 41.

North Island Hydraulic Survey Party - Hydrometric recordings taken by the North Island Hydraulic Survey Party. This party ceased to operate on 1 January 1968 and operations transferred to Ministry of Works and Development Palmerston North office (Agency Code 80), but gauging card number sequence is continuous. Agency Code 70.

Sir Alexander Gibb and Partners - Hydrometric Recordings taken by Sir Alexander Gibb and Partners.  Sir Alexander Gibb & Partners was a British firm of consulting civil engineers, based at Queen Anne's Lodge, Queen Anne's Gate. The firm had been founded in 1922 by noted Scottish civil engineer, Brigadier-General Sir Alexander Gibb. The firm undertook a number of important hydro-electric dam projects including the design and supervision of Tongariro Hydroelectric Scheme. Agency Code is 71.
