values and water quality objectives 1 Introduction This document is made pursuant to the provisions of the Environmental Protection (Water) Policy 2009 (the EPP [Water]), which is subordinate legislation under the Environmental Protection Act 1994 . The EPP (Water) provides a framework for: • identifying environmental values for Queensland waters, and deciding the water quality objectives to protect or enhance those environmental values; and • including the identified environmental values and water quality objectives under Schedule 1 of the EPP (Water). This document contains environmental values and water quality objectives for waters in the Logan River catchment, and is listed under schedule 1 of the EPP (Water). 1.1 Waters to which this document applies This document applies to fresh, estuarine and marine surface waters and groundwaters draining the Logan River catchment, as indicated in the accompanying plan (WQ1454)1. These waters fall substantially within the broader South Coast basin (basin 145)2. Waters covered by this document include: • Logan River including both freshwater and estuary; • California Creek; • Native Dog Creek; • Serpentine Creek; • Slacks Creek; • tidal canals, constructed estuaries, marinas and boat harbours; • Lake Maroon; • Christmas Creek; • Running Creek; • Knapps Creek; • Teviot Brook; • other freshwater and estuarine waters in the Logan River estuary catchment; • wetlands; and • groundwaters. The geographical extent of waters addressed by this document is shown in the plan (WQ1454), and is broadly: • north to the boundary of the Logan River catchment with the Redland and Brisbane catchments, and to the boundary of Bremer River catchment; • west to boundary of the Logan River catchment with the Brisbane and Bremer catchments; • south to the boundary of the Logan River catchment; and • east to the boundary of the Logan River catchment with the Albert River catchment and Moreton Bay. 1This document and the accompanying plan are available in electronic form from the Environmental Values web page on the Department of Environment and Resource Management (DERM) website : http://www.derm.qld.gov.au/ . The boundaries in the accompanying plan WQ1454 are indicative only. The water types and management intent depicted in the accompanying plan are stored in electronic form as part of the SEQ Environmental Values Schedule 1 Database July 2010 and held at the DERM offices at 41 George Street Brisbane. Database regions are based on the regions established in the Queensland water quality guidelines .

Daniel Des Rex Owen BNatRes MSc (Research) Submitted in fulfilment of the requirements for the degree of Doctor of Philosophy School of Earth, Environmental and Biological Sciences Science and Engineering Faculty Queensland University of Technology 2016 Keywords Aquifer interactions; Bromide; Carbon isotopes; Chloride; Coal seam gas; Coal bed methane; Compositional data analysis; Dissolved Organic Carbon; Hydrochemical indicator; Hydrogen isotopes; Inverse modelling; Isometric log ratios; Lithium; Major ions; Methane; Methanogenesis; Multivariate statistics; Sodium-bicarbonate groundwater; Stable isotopes of lithium; Stable isotopes of chlorine; Thermodynamic controls Hydrochemical and isotopic indicators of hydrological processes within coal seam gas formations and adjacent aquifers, Condamine River catchment, QLD. i Abstract In areas where a range of industries and economies rely on the extraction of water, aquifer connectivity can be a controversial issue and in some cases it may lead to water resource conflict- and management-challenges. Recently, the expansion of the coal seam gas industry has raised concerns about the risks to aquifers adjacent to gas-bearing aquifers because water needs to be extracted from the coal seams in order to release the sorbed gas. Consequently, there is a need to: a) understand aquifer connectivity in particular areas; and b) critique the effectiveness of different parameters that can be applied to understand interactions between coal seam gas formations and adjacent aquifers. This study provided a hydrochemical and isotopic assessment within and between a coal measure aquifer (the Walloon Coal Measures) that is being exploited for coal seam gas reserves, and a large, agriculturally- important alluvial aquifer (the Condamine River alluvium), in south east Queensland, Australia.

Kennard Bachelor of Science Master of Philosophy Centre for Riverine Landscapes, Faculty of Environmental Sciences, Griffith University, Brisbane, Australia. A thesis submitted in fulfilment of the requirements of the degree of Doctor of Philosophy 2005 ii Synopsis In response to increasing community concern with declines in the ability of aquatic ecosystems to deliver critical goods, services and long-term benefits to human society, there is greater recognition of the need for quantitative procedures to assess aquatic ecosystem health and monitor biotic responses to remedial management. This thesis aims to evaluate the potential to incorporate attributes of freshwater fish assemblages into an ecosystem health monitoring program for wadeable rivers and streams in coastal catchments of south-eastern Queensland, Australia. I identify five key requirements of a quantitative and defensible river health assessment program that need to be evaluated before indicators based on fish can be validly applied for river health assessment in the region. The five requirements are: 1) quantification of error associated with sampling fish; 2) assessment of natural ranges of spatial and temporal variation in fish assemblage attributes; 3) accurate definition of the reference condition expected for these attributes in the absence of human disturbance; 4) demonstrated relationships of the indicators with disturbance; and 5) evaluation of potentially important confounding environmental and biological factors.
