Established in 2009, the Ecosystem Health Assessment Program (EHAP) is a partnership approach to monitoring and reporting on the ecosystem health of the Tamar estuary.
The EHAP monitoring covers the entire length of the Tamar estuary and has 16 monthly ambient monitoring sites from Home Reach in Launceston, to Low Head at the mouth of the kanamaluka/Tamar near George Town.
The estuary is divided into five functional zones. Zones 1 to 3 (Launceston to Rowella) are considered to be estuarine, with zone 1 receiving the freshwater from the Esk rivers. Zones 4 and 5 are marine and are strongly influenced by the marine waters of Bass Strait.
The monthly monitoring data is collated and used to produce the Tamar Estuary Report Card, summarising the quality of the water in grades that relate to ecosystem health. Pressures and drivers of water quality change are identified for the 12-month reporting period.
Water quality parameters sampled each month include: pH, electrical conductivity, turbidity, dissolved oxygen and water temperature are collected at each site through the water profile. The surface water is also tested for nutrients, metals, bacteria and chlorophyll-a. The data is used to produce report cards based on a 12-month period that includes the four seasons.
Data outside of the EHAP program is welcomed by TEER and may be stored in the TEER database for future use and access. Please contact us if you wish to contribute.
Data is available to businesses and students investigating conditions and scenarios associated with the kanamaluka/Tamar estuary. Please contact us to speak with a member of the NRM North TEER team if you would like to learn more.

Working together to protect, restore and enhance the Tamar Estuary and Esk Rivers systems from 'catchment to coast'.
Catchment works to improve public health through reduced pathogen concentrations in Zone 1 of the kanamaluka/Tamar estuary.
