# 5.11 - StateMod Formatted Crop Irrigation Water Requirement File (*.ddc)

The StateMod formatted crop irrigation water requirement file (*.ddc) is generated when the variable ddcsw= 1 and isuply= 1 in the model control file (see Section 4.4). This output file, like the *.cir file, contains the estimated monthly crop irrigation water requirements for each structure. However, it is written in the standard StateMod format in calendar year format for time series information. The crop irrigation water requirement file (*.ddc) is used by in StateDMI along with efficiency estimates to create the StateMod ‘calculated’ direct diversion demand file (*.ddm). An example is provided in Appendix A.
