The Sacramento County Hydrologic Calculator (SacCalc) calculates design flows using Sacramento County Hydrology standards. SacCalc replaces the older DOS-based SACPRE program that prepared input files for the US Army Corps of Engineers HEC-1 program. SacCalc is a Microsoft Windows application that provides a graphical user interface for watershed layout and design storm selection. SacCalc can also provide Nolte flows used for storm drain design in Sacramento County.
