Introduction

The following set of notes provides water accounting statements for each of the water stores and systems within the Adelaide region during the 2013–14 year. Information on all water flows to and from each water store and system are presented in this note, including between-store flows and transfers that are not presented in the consolidated water accounting statements (which are shown in italics).

For more information about the region, please refer to General description section in 'Contextual information'. For more information on between-store flows and transfers that occur in the region, please refer to the Supporting information note.
