Circular Head and Waratah Wynyard Catchments DEPARTMENT of PRIMARY INDUSTRIES, WATER and ENVIRONMENT ENVIRONMENTAL MANAGEMENT GOALS for TASMANIAN SURFACE WATERS CATCHMENTS WITHIN THE CIRCULAR HEAD & WARATAH/WYNYARD MUNICIPAL AREAS January 2000 Environmental Management Goals For Tasmanian Surface Waters: Circular Head and Waratah/Wynyard Municipal Areas This discussion paper was used as a basis for community and stakeholder participation in the process of developing environmental management goals for the waterways that are located within the Circular Head and Waratah/Wynyard municipal areas. The Pieman Catchment is partially within the West Coast municipal area. The discussion paper was prepared by the Environment Division in association with the Land and Water Management Branch, of the Department of Primary Industries, Water and Environment. The discussion paper was initiated from a workshop held with council officers from the Circular Head and Waratah/Wynyard Councils in July 1999. Words and expressions used in this discussion paper have, unless the contrary intention appears, the same meaning as defined in the State Policy on Water Quality Management 1997 and the Environmental Management and Pollution Control Act 1994. Ecosystem refers to physical, chemical and biological aspects of the aquatic environment. This discussion paper is divided into four main sections: 1. The first section discusses water reform in general, the State Policy on Water Quality Management and gives some general information relating to the area included in the discussion paper (Sections 1-3). 2. The second section discusses the proposed Protected Environmental Values for individual catchments. There is some repetition in this section because the discussion paper was designed so that individual catchment PEVs can be read in isolation from the rest of the document (Section 4). 3. The third section discusses water quantity values (Section 5). 4. The fourth section shows the community water values that were obtained from community workshops and public meetings (Section 6). 2 CONTENTS 1 INTRODUCTION............................................................................................................................4 1.1 WHY DO WE NEED WATER REFORM? .......................................................................................4 1.2 WHAT ARE THESE REFORMS?....................................................................................................4 1.3 WHAT WILL THIS COMMUNITY INPUT ACHIEVE? ...................................................................5 1.4 WHAT INFORMATION DID WE RECEIVE FROM THE COMMUNITY?........................................5 1.5 HOW WILL YOUR INPUT BE USED?............................................................................................5 2 CIRCULAR HEAD AND WARATAH/WYNYARD CATCHMENTS OVERVIEW ..............6 2.1 CATCHMENT DESCRIPTION........................................................................................................6 2.2 CHARACTERISTIC WATER QUALITY .........................................................................................7 2.3 CATCHMENT ENVIRONMENTAL ISSUES ...................................................................................8 3 WATER QUALITY : THE STATE POLICY ON WATER QUALITY MANAGEMENT.....9 3.1 SETTING PROTECTED ENVIRONMENTAL VALUES ..................................................................9 3.2 PROTECTED ENVIRONMENTAL VALUES CATEGORIES...........................................................9 3.3 COMMUNITY INPUT ..................................................................................................................10 4 WATER QUALITY : PROTECTED ENVIRONMENTAL VALUES FOR YOUR CATCHMENT .........................................................................................................................................11 4.1 PIEMAN RIVER CATCHMENT .............................................................................................12 4.2 ARTHUR RIVER CATCHMENT .............................................................................................24 4.3 WELCOME RIVER CATCHMENT .........................................................................................35 4.4 MONTAGU RIVER CATCHMENT ........................................................................................43 4.5 DUCK RIVER ............................................................................................................................49 4.6 BLACK & DETENTION RIVERS, CRAYFISH CREEK AND SISTERS CREEK ...............58 4.7 INGLIS/FLOWERDALE RIVERS............................................................................................66 4.8 HEADWATERS AND WESTERN SIDE OF CAM RIVER CATCHMENT...........................74 4.9 HEADWATERS OF EMU, BLYTH AND LEVEN RIVERS...................................................79 5 WATER QUANTITY: WATER QUANTITY VALUES...........................................................81 5.1 OVERVIEW.................................................................................................................................81 5.2 WATER QUANTITY VALUES.....................................................................................................81 6.

  • A Review of Geoconservation Values
    Geoconservation Values of the TWWHA and Adjacent Areas 3.0 GEOCONSERVATION AND GEOHERITAGE VALUES OF THE TWWHA AND ADJACENT AREAS 3.1 Introduction This section provides an assessment of the geoconservation (geoheritage) values of the TWWHA, with particular emphasis on the identification of geoconservation values of World Heritage significance. This assessment is based on: • a review (Section 2.3.2) of the geoconservation values cited in the 1989 TWWHA nomination (DASETT 1989); • a review of relevant new scientific data that has become available since 1989 (Section 2.4); and: • the use of contemporary procedures for rigorous justification of geoconservation significance (see Section 2.2) in terms of the updated World Heritage Criteria (UNESCO 1999; see this report Section 2.3.3). In general, this review indicates that the major geoconservation World Heritage values of the TWWHA identified in 1989 are robust and remain valid. However, only a handful of individual sites or features in the TWWHA are considered to have World Heritage value in their own right, as physical features considered in isolation (eg, Exit Cave). In general it is the diversity, extent and inter-relationships between numerous features, sites, areas or processes that gives World Heritage significance to certain geoheritage “themes” in the TWWHA (eg, the "Ongoing Natural Geomorphic and Soil Process Systems" and “Late Cainozoic "Ice Ages" and Climate Change Record” themes). This "wholistic" principle under-pinned the 1989 TWWHA nomination (DASETT 1989, p. 27; see this report Section 2.3.2), and is strongly supported by the present review (see discussion and justification of this principle in Section 2.2).

Distribution of acid sulphate soils in Tasmania Dr Shivaraj Gurung FOREWORD Acid sulphate soils are pyritic sediments that can produce acid when exposed to oxidising conditions. These sediments typically occur in low-lying coastal areas, backswamps and in estuarine environments. The acid drainage resulting from the disturbance of acid sulphate soils can dissolve and mobilise toxic metals which can enter the receiving environment, causing serious damage to the aquatic ecosystem. Acid water and heavy metal pollution from the disturbance of acid sulphate soils is a major strategic environmental issue for management of coastal regions around Australia. Section 36.1 of the Tasmanian State Policy on Water Quality Management (1997) requires that “a survey is carried out to identify Tasmanian soils and surface geology with the potential to give rise to highly acidic drainage if disturbed or developed”. This reconnaissance investigation provides a basis for this objective. The program is a component of the proposed State Water Quality and Quantity programs and was largely funded by the National Heritage Trust. Water analyses were carried out by the Department of Primary Industries, Water and Environment at the Analytical Services Tasmania laboratory. Geochemical analyses, map production and project management were carried out by Mineral Resources Tasmania.

During a broad study of the biology of the freshwater in rhe Tasmanian genus fWO distinct forms of Astacopsis franklinii were recognised. These "forms" were found to diffcr in terms of their general morphology and distribution. As a result, the taxonomy of Astacopsis has been revised to re-establish the three species originally described by Ellen Clark. Astacopsis franklinii Gray has been divided into fWO separate species, the eastern Astacopsis franklinti and the western Astacopsis tricorn is, while the status ofArtacopsis gouldi remains unaltered.
