In 1993 the Wainuiomata Water Resources Statement was produced.
This document described the water resource and characteristics of the
Wainuiomata Catchment.

This report, Hydrology of the Wainuiomata Catchment, serves to restate
the catchment characteristics and to update the surface water hydrology
component of the Wainuiomata Water Resource Statement. It solely
considers the surface water hydrology of the Wainuiomata catchment.

The purpose and objectives of this report are:
1. To collate all available information, data and past reports on the
surface water resources of the Wainuiomata Catchment,
2. To carry out analyses on hydrological data, and
3. To present this hydrological data in a format suitable for use by the
Council and other agencies in the resource consent process.
