A spill allocation is a type of off-quota allocation applied to a planning area or group that is consumed during a spill entitlement period. See <u>[Managing Off-Allocation (aka Off-Quota) Periods](https://rubiconwater.atlassian.net/wiki/spaces/PNC/pages/2051899709)</u> for more information about off-quota periods in general.

If you designate a spill entitlement period, any water supplied to an authorisation during that period is tallied against its **Spillage Sales** attribute. The maximum amount of water that can be supplied as spill during a period is set in the **Maximum Spillage Usage ML** attribute for the planning area or group.

# Create a spill allocation

1. In the Planning Groups or Planning Areas module, select the planning group or area.
2. On the Attributes tab, select the **Maximum Spillage Usage ML** attribute and click **Modify**.
3. Enter the total spillage allowed for the season and click **Save**.

# Create a spill entitlement period

2. On the Spill Allocation tab, click **Insert** to add a new Spill Entitlement
3. Set the **Type** to *Spill Entitlement*.
4. Specify the start and finish time and date. (Note that periods cannot overlap.)
5. Click **Save** to save your changes.

Any water usage during the period will be counted as spill. If there is no spill allocation remaining, any further usage will be counted against the standard allocation.
