A future Lower Lakes Barrage Operating Strategy is to be developed – details of which will be made available in the future. Other schedules to this plan may be developed as required.
GLOSSARY OF TERMS
Attractant flow — flow designed to provide a physical or chemical stimulus for fish to utilise a fishway.
Aquatic ecosystem – any water environment from small to large, from pond to ocean, in which plants and animals interact with the chemical and physical features of the environment.
Basin Officials Committee (BOC) — a jurisdictional committee to coordinate the management of Basin water resources between the Commonwealth, the Authority and the Basin States.
Coorong — general title used for the 140 km long expanse of water, separated from the Southern Ocean by a narrow dune barrier encompassing both the North and South lagoons.
Diadromous species — a species which moves between fresh and salt water.
Diurnal Tidal Ratio (DTR) — a measure of the tidal energy fluctuations in the Coorong estuary relative to that in the ocean. Used as a measure of Murray Mouth openness. A value of one (1) indicates tides in the Coorong are equal in range to those in the ocean.
Ecological Objectives — an objective is a statement of the desired condition. It is not necessary to quantify an objective.
Ecological Targets — a target is generated from the ecological objective and will ideally be quantitative.
Electrical Conductivity (EC) — the ability of water or soil to conduct an electric current; commonly used as a measure of salinity or total dissolved salts. One EC unit is equal to one micro Siemens per centimetre at 25°C (μS/cm-1).
Environmental Water — water that is available for the environment.
Environmental Watering Group (EWG) — a jurisdictional committee that develops and implements the annual TLM Environmental Watering Plan. The EWG recommends annual TLM watering priorities and proposals to ensure consistency between icon sites
Estuarine species — a species which either resides in, relies upon for the completion of a life stage, or opportunistically utilises the estuarine environment.
Euryhaline species — are those which are capable of tolerating a wide salinity range, i.e. freshwater to marine.
Flow regime — a flow regime is a specific combination of the timing, volume, frequency and duration of flow events in river systems.
Icon Site Environmental Watering Plan — A plan that details the aims, objectives and management actions at an icon site that are in accord with The Living Murray program. The plan is complementary to state based plans and processes.
Krinkari — Ngarrindjeri term for ‘non-Indigenous’ people.
Kurrangk — Ngarrindjeri term for the area referred to by Krinkaris as the Coorong.
Kungun Ngarrindjeri Yunnan agreements — a negotiation and contract (agreement) making methodology known as Kungun Ngarrindjeri Yunnan (KNY) (listen to what Ngarrinderi people have to say). Ngarrindjeri use this methodology in significant interactions with government and other non-Indigenous interests impacting on Ngarrindjeri Ruwe/Ruwar (see Hemming & Trevorrow 2005; Hemming, Rigney & Berg 2011). This approach has been adopted by the new Ngarrindjeri nation’s peak body, the Ngarrindjeri Regional Authority (NRA).
Littoral — the edge or shallow area of a water body.
Lower Lakes — Lake Alexandrina and Lake Albert.
Marine straggler — marine fish species which enter an estuary infrequently and in low numbers.
Murray–Darling Basin Authority — previously the Murray–Darling Basin Commission.
Murray–Darling Basin Commission — now the Murray–Darling Basin Authority.
Murray–Darling Basin Ministerial Council (Ministerial Council) — Ministerial Council who develops and agrees to the Intergovernmental Agreements, approve The Living Murray Business Plan and make key decisions.
Murray Mouth estuary — usually defined as the region between Goolwa Barrage and Pelican Point.
Ngarrindjeri Regional Authority (NRA) — Ngarrindjeri contemporary governing organisation recognised by State and Federal governments as the peak governing body for the Ngarrindjeri nation. The NRA Board includes representation from the Ngarrindjeri Native Title Management Committee, the Ngarrindjeri Heritage Committee and the Ngarrindjeri Tendi.
Ngartji — for Ngarrindjeri people birds, animals, plants and all living things are spiritually connected – they are considered Ngartjis. A Ngartji is Ngarrindjeri totem – often referred to as a close friend and relative.
Ngurunderi — Ngarrindjeri creator ancestor: Ngurunderi creation ‘story’ is a primary Ngarrindjeri account of the creation in the Lower Lakes, Coorong and Murray Mouth region.
Objective — refer ‘ecological objectives’.
Obligate — by necessity, e.g. an obligate diadromous fish requires access to both fresh and salt water to complete its lifecycle.
Parameter — a measurable or quantifiable characteristic or feature.
Prograded — built out; a term that refers to areas of lake edge where elevated water levels have caused erosion of the sediment underneath the topsoil, resulting in a ‘shelf’.
Ramsar — a global treaty adopted in the Iranian city of Ramsar in 1971 that focuses on the conservation of internationally important wetlands.
Ruwe/Ruwar — Ngarrinderi ontology: represents the interconnectedness between lands, waters, body, spirit and all living things.
Target — refer ecological target.
Tendi — The traditional Ngarrindjeri governing body.
The Living Murray Committee (TLMC) — A jurisdictional committee who is responsible for the implementation of The Living Murray Business Plan.
Water Requirements — includes the flow, volume, timing, duration, velocity, depth, quality or any other attribute that is required to meet the ecological target.
Yarluwar-Ruwe — Ngarrindjeri ‘Sea Country’: represents the interconnectedness between what western traditions understand as sea and land, fresh water and salt.
