Rocky Valley Reservoir does not form part of the entitlement system within the MDB region. It is a storage owned by a hydro-electric operator and the volume released each year is subject to their water licence. No orders can be placed on the storage for delivery of water to the entitlement system. It does not reflect a volume that can be used to support the total volume in storages. It is potentially an asset, although there is some doubt about when the asset can be claimed because it is not available to settle claims for water until the hydro-operator physically makes the release.
