INTRODUctION This document and its package of supporting The introduction of the ACT Water Resource Plan instruments and texts constitute the ACT Water (WRP) sets out the water management arrangements Resource Plan for surface water and groundwater for both surface water resources and groundwater (Water Resource Plan). The water resource plan is the in the ACT to share water for consumptive use and key instrument through which several elements of the to meet environmental and water quality objectives. Murray‑Darling Basin Plan 2012 will be implemented in In doing so, it builds on the ACT statutory water the water resource plan area. planning arrangements and the ACT Water Strategy: Striking the Balance 2014–2044, which was developed S63 of the Water Act 2007 (Cth) requires a Basin State in consultation with key stakeholders and regional to prepare a water resource plan for each of its water communities. Much of the response is common to resource plan areas for accreditation. The water both the surface water WRP and the groundwater WRP. resource plan is the key instrument through which several elements of the Basin Plan are to be achieved. D ACT WatER RESOURCE PLAN 2. THE ACT WatER RESOURCE PLAN AREA 2.1 DESCRIptION OF THE For s10.03 of the Basin Plan, the following SDL resource units and water resources within those ACT WatER RESOURCE units are identified: Plan area > the Australian Capital Territory (surface water) In developing the ACT’s WRP it is critical to note the water resource plan area—the SDL resource unit geographical context and historical background named ‘Australian Capital Territory (surface water) of the ACT. The ACT broadly consists of two (SS1)’, and the water resources within that unit, as physiographic regions: the south‑west dominated described in s6.02 and Schedule 2 of the Basin Plan. by the Brindabella Mountain Range and the Australian Note that the surface water of the Googong Dam Alps; and the north‑east portion, the Werriwa Area (within the meaning of the Canberra Water Tablelands, which comprise upland plains with Supply (Googong Dam) Act 1974) is to be treated as if separate upland hills and basins. it were in the ACT.

Murrumbidgee River catchment and the subsequent purpose of the Territory’s water use affect how and Because of the unique nature of the ACT water how much water resources are used. The ACT is the resources it is necessary to apply s3.04 of the largest urban area within the Basin. Its land use is Basin Plan which provides for flexibility relating predominantly national parkland with a large urban to boundaries of water resource plans. Therefore, and administrative centre, with limited agriculture. the identification of the water resource plan area There are four water storage/supply dams (Corin, (requirement s10.02) is described as: Bendora, Cotter and the Googong Dam (latter located > the Australian Capital Territory (surface water) in NSW) on the Cotter River and the Queanbeyan River, water resource plan area and all surface water tributaries of the upper Murrumbidgee River. resources in that area as described in Part 2 of Chapter 3 of the Basin Plan, and The Upper Murrumbidgee catchment (within which the ACT is located) is a regulated catchment that > the Australian Capital Territory (groundwater) covers an area of 13,000 km2, of which the ACT water resource plan area and all groundwater occupies 2,400 km2. The Murrumbidgee River rises resources in that area as described in Part 2 in the south‑western part of the catchment in NSW of Chapter 3 of the Basin Plan. within the Snowy Mountains. It flows some 30 km before reaching Tantangara Dam, where much of its flow is diverted to Lake Eucumbene under the Snowy Mountains Scheme. The river then flows downstream for 150 km through the ACT and NSW, to discharge into Burrinjuck Dam to the north of the ACT. 2 ACT WatER RESOURCE PLAN Characteristics of ACT rivers and streams The Murrumbidgee River and its tributaries is a key geomorphic, hydrological and ecological feature of In the context of the Murray–Darling Basin, the the ACT.
