Council recently commissioned two water quality assessments as background studies for a new Tweed River Estuary Management Program currently being prepared.
Both examined compliance with aquatic ecosystem protection targets for the Tweed River and Terranora-Cobaki Broadwaters between 2012 and 2016.
Read the reports.

Council undertakes regular water quality monitoring in the freshwater and estuarine reaches of the Tweed River, and the Tweed Coastal Creeks.
Data is collected and analysed by the Tweed Laboratory, and is regularly reviewed in order to present the findings of these investigations.
The Tweed Laboratory Centre is a multi-million dollar facility offering a comprehensive range of chemical and biological testing for soil and water.
The following reports present these findings.

Tweed Estuary Water Quality Review 2007-2011 - Final Report
Tweed Shire Council has undertaken a water quality monitoring program in the Tweed estuary since 2007. The data span a wide range of wet and dry climatic conditions and therefore provide a comprehensive picture of water quality variation in the Tweed estuary. This report provides an analysis of temporal and spatial trends in water quality, identifies likely controlling processes and discusses ecological implications.

Cudgera Creek and Kerosene Inlet, Fingal Head
Australian Wetlands was commissioned by the Tweed Shire Council (TSC) to undertake a baseline ecological health assessment for the Cudgera Creek estuary at Hastings Point and Kerosene Inlet on Letitia Spit Fingal Head, NSW. The project involved the collection and identification of benthic macroinvertebrates, water and sediment quality assessment as well as on-site assessment of seagrass health.

Cobaki and Terranora Broadwater Ecosystem Health Monitoring Program
This report card shows the results of an estuary health investigation conducted by Tweed Shire Council in Cobaki and Terranora Broadwaters and their catchments. Water Quality and other estuary health indicators, for example sea grass condition, have been measured for 12 months, and the results analysed to provide a description of the overall condition of the entire system.
