Initial Request
The methods in this category specify how the storage account calculates the Initial Request in the water rights allocation. The methods in this account are valid only if the account has a water right as specified by the Priority Right method.
* None
No initial request is necessary, no appropriation is made, and no slots are added. This is the default method.
* Specify Initial Request
This method allows the user to specify the initial appropriation request for use in a prioritized water rights allocation.
Slots Specific to This Method
 Initial Request
Type: Series Slot
Units: Flow
Alternate Units: Volume
Description: The initial water rights appropriation request
I/O: Required user Input or Rules
 Shortage
Type: Series Slot
Units: Flow
Alternate Units: Volume
Description: The difference between the Initial Request and the Flow slot.
I/O: Account-level Method
* Based on Reference Level
This method is valid only if the Reservoir Storages Lookup method in the Instream Flow Reference Level category is selected on the containing control point. This method creates a slot named Reference Level, which is a slot with a one-year timestep, whose value is computed once per year at the date indicated in the Start of Reference Year (also on the containing control point). See Reservoir Storages Lookup in Objects and Methods for additional information on the Reservoir Storages Lookup method.
This method is executed at the beginning of the timestep to look up the current timestep and the Reference Level (on the control point) on the Reference Level Stream Flow Table to determine the Initial Request for the timestep.
Note:  If the current timestep is before the Start of Reference Year, the Reference Level used to compute the Initial Request is that of the prior year. This means that you must input an initial Reference Level if the Start of Reference Year does not coincide with the start of the run.
Slots Specific to This Method
 Reference Level Stream Flow Table
Type: Periodic
Units: Time vs Flow
Alternate Units: NA
Description: The periodic slot maps the reference level (as columns) from the underlying control point slot to an initial request (flow values in the table).
I/O: Input Only
 Shortage
Type: Series Slot
Units: Flow
Alternate Units: Volume
Description: The difference between the Initial Request and the Flow slot.
