The Tamar Estuary Management Taskforce (the Taskforce) was established under the Launceston City Deal with an aim of identifying investments to improve the health of the Tamar Estuary. As part of this work, the Taskforce was charged with delivering a River Health Action Plan (this Plan) by the end of 2017.
Influences that have all been cited as reasons for the Tamar not meeting modern expectations of health and amenity include:
- the City’s combined sewerage and stormwater system,
- the inability to flush sediment due to marine tides meeting freshwater rivers,
- agricultural practices further up in the catchment,
- historical industrial practices,
- outflows from multiple waste water treatment plants throughout the Estuary,
- river floods and man made changes to the flow and channel of the Estuary
The Taskforce identified the initial priority was to improve public health measures of water quality in the estuary between Launceston to Legana.
Catchment actions to the value of $10 million to be implemented across dairy, grazing and urban areas. These actions aim to exclude stock from streams, rehabilitate riparian vegetation buffers on grazing properties, ensure better effluent management on dairy farms and remove sewage intrusion into separated stormwater system in urban areas around Launceston. These actions are expected to reduce pathogen concentrations in the Launceston to Legana zone of the estuary by more than 4 per cent.
