This report presents an analysis of patterns of low flow in the Ruamahanga River catchment over past decades. Several indicators of rainfall and river flow are assessed for time trends and patterns. A discussion is provided about the extent to which patterns can be attributed to natural (e.g. climate cycle) and/or non-natural (e.g. water abstraction) drivers.
