Water asset accounts
Information presented in the water asset accounts
In this section water assets are presented using the System of Environmental-Economic Accounting (SEEA) framework. These water asset accounts present information, in physical units (e.g. ML), on the stocks (assets) of water resources at the beginning and end of an accounting period, as well as details on the increases and decreases in stocks. They present various water resource types (e.g. reservoirs, lakes, rivers, groundwater) as well as the water inflows (e.g. from upstream sources) and outflows (e.g. to other resources in the region) to each.
Comparison to water accounting statements
These accounts present similar information to the Statement of Water Assets and Water Liabilities and the Statement of Changes in Water Assets and Water Liabilities in the previous sections, albeit in a slightly different presentation. Note that the opening and closing stocks in these tables are aligned with those in the statements, and the increases and decreases are aligned with the inflows and outflows in the statement changes. The main difference between these SEEA-style tables and the statements is that increases and decreases in surface water stocks are further disaggregated (by reservoirs, lakes and rivers – e.g. Table S2). Another key difference is that all inflows and outflows between individual water assets/resources are presented in the SEEA-style tables; for example, flows into and out of each major reservoir are included. Minor differences in volumes of up to 1 ML between the water accounting statements and the water asset accounts may be present due to rounding.
Access to asset account tables
