Kovacova, E.; White, P.A. 2009 Groundwater catchments for individual springs in Ngongotaha and Waiowhiro surface catchments, Lake Rotorua. Lower Hutt, N.Z.: GNS Science. GNS Science report 2008/41 75 p.
Abstract: Recent groundwater research by GNS Science and Environment Bay of Plenty estimated the catchment areas of major hydrological features such as springs and spring-fed streams, in the whole Lake Rotorua catchment as part of investigations into groundwater and Lake Rotorua water quality. This report aims to assess groundwater catchments of two Lake Rotorua surface catchments in greater detail than recent research by identifying catchment of 50 major and minor springs in the Ngongotaha and Waiowhiro surface catchments.
