Executive summary This report canvasses the key features of current surface water management in the Macquarie catchment upstream of the junction with the Lake River. The report addresses roles and responsibilities, water development, administrative requirements, water allocations, formal management arrangements, access rules, restriction management and actual management practice. The key features of water management in the Macquarie catchment are: • A long history of water development, with three large storages in the upper catchments: Lake Leake on the upper Elizabeth River, Tooms Lake in the Upper Macquarie catchment and most recently, Blackman Dam on the upper Blackman, and many privately owned storages including three very large dams (Winton, Glen Morriston and Trefusis). • As a result, much of the water used for irrigation in the Macquarie River catchment is supplied by regulated flows. • The Macquarie catchment is part of the South Esk Basin Hydro District (comprising the Meander, South Esk, Brumbys-Lake and Macquarie Rivers) and is expected to be a ‘receiving’ catchment for the

Good days, but more bad days on the Great Lake, and some good jassid falls at the end of the season. In the north of the state, it was a similar story. Significant rain washed away the hoppers from the river banks and the usually reliable hopper fishing went with On Sunday 27th March some of the members met it. However, Four Springs produced good hatches at patron Barbara Fowler‟s lovely property, and some outstanding fishing days. How I wish Bendeveron, for the annual casting day. What a we had a Four Springs lake in the south of the beautiful autumn day. The Margaret Knight Dry state.

Lower down, Whilst the casting is a bit of fun among members Tooms Lake and Meadowbank should be worth a there is no doubt that casting practice will look earlier in the season.

In these chapters, as in the entire work, the use and expression of units is as recommended in "Style manual for authors, editors and printers of Australian Government publications" (third edition, Commonwealth of Australia, 1978). Abbreviations and symbols used are as follows: number in sample S.D. standard deviation Student's t 2 X chi-squared d.f. degrees of freedom probability n.s. not significant at the level p=0.05 significant at the level p=0.05 ** significant at the level p=0.01 *** significant at the level p=0.001 Other abbreviations and symbols are explained in the text. 184 CHAPTER FIVE ENVIRONMENT A description of the Anglers Creek study site: methods, results and discussion. Section 5.1 Location and Access 2 The study site chosen was an area of about 3000 m of low closed-forest (Specht, 1970) near Anglers Creek, on Moaners Tier, 3 km southeast of Tooms Lake and 17 km from the east coast of Tasmania (Figure 5.1 and Plate 5.1). The Jurassic dolerite intrusions in east- ern Tasmania have given rise to a series of low plateaus, or tiers (Davies, 1965). Moaners Tier is a smaller example which rises to 750 in near the study site, which is at an altitude of 600 m. There 0 is a northerly slope of 5 in the study area, of which no part is closer than 20 in to Anglers Creek.

    Abduction and Multiple Killings of Aborigines in Tasmania: 1804-1835 Lyndall Ryan, Author, The Aboriginal Tasmanians, Visiting Fellow, Genocide Studies Program, Yale University, and Honorary Conjoint Professor School of Humanities and Social Sciences Faculty of Education & Arts University of Newcastle Ourimbah Campus, N.S.W., Australia Email: [email protected] Introduction Tasmania (known as Van Diemen’s Land until 1855) is about the same size as Ireland and a little smaller than Sri Lanka. Physically it is part of the continent of Australia but became separated from it by the formation of Bass Strait during the Holocene era about 10,000 years ago. The island was occupied for at least 30,000 years by a hunter-gatherer people, the Tasmanian Aborigines. Contrary to a long and widely held belief that they were a ‘stone age’ people who were destined to die out as a result of 10,000 years of isolation from the Australian mainland, recent archaeological research indicates that they were a dynamic people who not only reshaped their culture and society during the Holocene era, but were increasing in population at the moment of British colonization in 1803 (Lourandos 1997:281). Recent research estimates the Aboriginal population in 1803 at between 4,000 and 9,000 (Jones 1974:325; Butlin 1993:133-4). By 1835 however, fewer than 200 Aborigines remained. What had happened to the rest? Most historians acknowledge that a bloody war took place between the Aborigines and the British colonists for possession of the island between 1823 and 1835 but disagree about how many Aborigines lost their lives.

  • A Compilation of Place Names and Their Histories in Tasmania
    LA TROBE: Renamed Latrobe. LACHLAN: A small farming district 6 Km. south of New Norfolk. It is on the Lachlan Road, which runs beside a river of the same name. Sir John Franklin, in 1837, founded the settlement, and used the christian name of Governor Macquarie for the township. LACKRANA: A small rural settlement on Flinders Island. It is 10 Km. due east of Whitemark, over the Darling Range. A district noted for its dairy produce, it is also the centre of the Lackrana Wildlife Sanctuary. LADY BARRON: The main southern town on Flinders Island, 24 Km. south ofWhitemark. Situated in Adelaide Bay, it was named in honour of the wife of a Governor of Tasmania Sir Harry Barron. Places with names, which are very similar often, created confusion. LADY BAY: A small bay on the southern end of DEntrecasteaux Channel, 6 Km. east of Southport. It is almost deserted now except for a few holiday shacks. It was once an important port for the timber industry but there is very little of the wharf today. It has also been known as Lady's Bay. LADY NELSON CREEK: A small creek on the southern side of Dilston, it joins with Coldwater Creek and becomes a tributary of the Tamar River. The creek rises inland, near Underwood, and flows through some good farming country. It was an important freshwater supply in the early days of the colony. LAGOONS: An alternative name for Chain of Lagoons. It is 17 Km. south ofSt.Marys on the Tasman Highway. A geographical description of the inlet, which is named Saltwater Inlet, when the tide goes out it, leaves a "chain of lagoons".
