Deactivated nodes are indicated by a grey circle backlash symbol on top of the node icon. Deactivated links become a solid grey line. Figure 9 shows what happens when Middle Gauge the storage alone was deactivated using Deactivate (left pane), or Middle Gauge and the storage and all upstream components were deactivated using Multi-deactivate » This and all upstream, or Middle Gauge the storage and all downstream components were deactivated using Multi-deactivate » This and all downstream (right pane).

Note the following about deactivation:
- Multi-deactivate and multi-activate does not work if traversing the network leads back to the starting component. Source will notify you if this occurs. For example, it is not possible to use multi-deactivate (either upstream or downstream) on either the environmental demand node or the water user node in Figure 9.
- Two Warning notifications are generated by Source when running a model with deactivated components:
- One indicates how many components were deactivated
- The other indicates how many components were excluded from the run order. Excluding components from the run order will reduce run time.
- Deactivation has not been implemented for a wetland cluster. If a component of a wetland cluster is deactivated, there will be a run time error.
- If a splitter is deactivated, all the flow, constituent and orders are passed down the non-effluent link.
- If a supply point is deactivated, the connected water user will not receive water.
