5.1 Surface water allocation remaining

Supporting information

The volume recognised in the water accounting statements (3,549 ML) represents the volume of surface water allocation remaining for individual user licence entitlements at the end of the 2011–12 year.

The Department of Land Resource Management administers 23 separate licences in this category held by individual licensees. Licences primarily relate to water sourced from the Katherine River for the agricultural and industrial sectors.

Method

The surface water supply licences for the region have a water management year that ends on 30 April. Therefore, the allocation remaining at the end of the 2011–12 year for the Daly region is the unused component of the annual allocation for these licences.

The allocation remaining was calculated as shown in the following table.
