How do I save my model files when working in the ArcMap environment?
In order to save your WaterGEMS for ArcMap file you need to open the Project Manager (View > Project Manager) from the program dropdown menu. After the window is open there is a save icon on top of it, which I've captured in the screen grab below. If the button is grayed out that means your model is already saved as the most current version.
