StateMod is the CDSS water allocation model. The modeling software is written in FORTRAN and the graphical user interface (GUI) is written in Java. TSTool, StateDMI, and other CDSS software prepare model data files using standard procedures that have been determined over years of CDSS development.
The downloadable StateMod software available on this website includes the StateMod Graphical User Interface (StateMod GUI), which is packaged with a version of StateMod. More recent versions of StateMod are maintained by the State of Colorado can be found on the State of Colorado's CDSS website.
It is not recommended to use the StateMod GUI to create and edit StateMod data sets because the software is not up to date with StateMod model features. Instead, use the StateDMI and TSTool software to automate creating StateMod data sets in a data-centered, repeatable approach. The StateMod GUI is useful for viewing data sets. Additional investment in the StateMod GUI may occur in the future.
