NSW Environmental Water Holdings
NSW holds water to use for environmental benefit, to increase environmental flows and return water-stressed environments to an acceptable level of health over time. The NSW Government purchased environment water at market rates though existing water markets. Recovery of water savings from infrastructure projects has also contributed to NSW Environmental Water Holdings. The purchase and recovery of water took place through a number of water recovery programs

Water categories and shares - Within regulated water sources, each water licence has a volumetric component or share of total water access for a particular category. The different categories reflect the long-term average reliability of water allocation which will vary with seasonal dam storage and inflows.
5. High security (HS) shares are likely to receive close to 100% of their allocation in most years.
6. General security (GS) allocation will depend on dam storage levels at the commencement of the year and seasonal inflows. Reliability varies between valleys from around 50% to 70% of full allocation on average.
7. Supplementary access (SA) shares are extraction rights for tributary and high river flows that are not captured by storage. Holders of supplementary water access licences are able to extract water only during announced flow events, with rostered or managed access in place in most water sources. Supplementary access events are typically announced when flows exceed those required to meet other licensed obligations and environmental needs; for example, as a result of high tributary inflows downstream of a dam or when the dam is spilling.
Units of measure: entitlements - units of measure for entitlement recovered are expressed in unit shares. Currently one unit share at full allocation is equivalent to one megalitre (ML).
8. Unregulated (UR) means not regulated by a major storage. For many valleys, water sharing plans for unregulated water sources have not yet been completed and licences are administered under the Water Act 1912.
9. Long-term cap equivalent (LTCE) - units of measure for entitlement purchased under The Living Murray Initiative which are converted by a modelled long-term reliability (CAP) factor and expressed as ‘long-term cap equivalent (LTCE)’, as per the The Living Murray Business Plan, and include all entitlement categories (HS, GS, SA, Conveyance).
