At the beginning of the project we completed a literature review and these are the reports we found relevant to the catchment:
Review of the Spring-Fed Coopers Creek, South Canterbury (Draft), Lincoln Ventures Limited, 2011
Report No. 1050-8-R1
Lincoln Ventures has undertaken a comprehensive review of the spring-fed Coopers Creek, located within the upper part of the Orari lowland catchment, South Canterbury

The Water Resources of the Orari River: de Joux, R 1980
Report No. XBES R24
This report summarises the knowledge held in 1980 on the quality, quantity and usage of water within the Orari River. Much of the information contained in this report remains relevant.

A geomorphologic Interpretation of the Orari, Waihi, Temuka and Opihi River Floodplains: Landcare Research, 1997
Report No. U97/36
Landcare Research, Lincoln undertook an aerial photograph interpretation-based assessment of the geomorphic setting of the Orari, Waihi, Temuka and lower Opihi floodplains as background for flood risk analysis by the Canterbury Regional Council in 1997

Low Flows of the Mainstem and Tributaries of the Orari and Temuka Rivers and Ohapi Stream: Scarf, F 2003
Report No. U03/38
This report summarises what was known, at 2003 about the low flows of the Orari and Temuka rivers, Ohapi Creek and other spring fed tributaries. Much of the low flow information previously published has been re-analysed taking into account abstraction occurring for irrigation, stockwater and domestic water supplies.

Integrated study of surface water and shallow groundwater resources of the Orari catchment: Burbery L and Ritson J 2010
Report No. R10/36
This report is the result of an intense field investigation made between 2006 and 2007 in the Orari hydrological catchment. The aim of the Orari Hydrological Catchment Investigation was to gather scientific data pertaining to surface water and shallow groundwater for the purpose of improving understanding about the interactions between surface and groundwater.

Update on ecology work: Burrell G 2010
This report provides an update on ecological field work undertaken by Golder Associates (NZ) Ltd in the Orari River catchment. The purpose of this report is to provide an update on what work has been undertaken to date, initial results and what further work is planned. A full report integrating results of fieldwork will be prepared on completion of all field work.

Orari Lagoon Update: Bower B 2011
CRC contracted Golder Associates (NZ) Ltd to investigate flows at the Environment Canterbury flood gate connecting Rhodes catchment to the main stem of the Orari River. Bower provided a pictorial update on the performance of a recorder installed at this location. This summary lacks a narrative explanation in particular for the hydrographs produced in the last pages. These hydrographs show the relationship (or lack thereof) between the recorder, tidal levels and wave height as well as the relationship between water levels at the lagoon, Orari River at the gorge and Orari River at the site known as upstream of Ohapi confluence (u/s Ohapi).

Hydro geological Support for the Orari Environmental Flow and Allocation Plan: Burberry L 2011
CRC contracted Lincoln Ventures Ltd. (LVL) to provide hydro geological support to the development of a flows and allocation plan for the Orari River catchment. This report documents the work completed by LVL for that purpose.

National Policy Statement for Freshwater Management 2011
The National Policy Statement for Freshwater Management 2011 sets out the objectives and policies for freshwater management under the Resource Management Act 1991. The freshwater NPS will help drive national consistency in local RMA planning and decision-making while allowing for an appropriate level of regional flexibility. This will support improved freshwater management in New Zealand.

These are the final technical reports:
Cultural Values & Flow Preferences of Te Runanga o Arowhenua for the Orari Catchment, Tipa Associates, 2012
This report describes a participatory process applied in the Orari Catchment in the South Island of New Zealand where Te Runanga o Arowhenua assessed the river flows necessary to protect cultural interests.

Coopers Creek Ecological Values and Flow Requirements Report, Golder Associates, 2013
The purpose of this report is to assess the ecological values of upper Coopers Creek in the vicinity of the springs, and to posit flow requirements to sustain those values.

Orari River Catchment Ecological Values and Flow Requirements Report, Golder Associates, 2013
This report analyses existing ecological information on water quality, periphyton, invertebrates, and fish, and examines relationships to river flows.

Orari River: Economic Impact of Minimum Flow Proposals, Harris Consulting, 2013
Because takes in the Orari catchment are very significant in relation to the size of the river, the amount of water used has a major impact on flows in the river.
