Hfam II is based on the Stanford, HSP, HSPF,  SRFM and Seafm family of models. It is a continuous simulation model that does historical or forecast analysis and it includes probabilistic or ensemble forecasts of streamflows, reservoir levels and releases or power production.

The HFAM II Dataprep program (Dataprep) is custom software developed by Hydrocomp, Inc to assist in the preparation of real-time meteorological data for use with HFAM II. The Dataprep program is customized for use in a particular watershed during the initial setup of the required Dataprep database and watershed map. The meteorological data required by HFAM II to simulate runoff and snow processes are precipitation, temperature, evaporation, solar radiation and wind speed. Dataprep can be used to prepare HFAM II input for any watershed, according to the watershed-specific information provided in the Dataprep database.

The distribution and use of hydrologic software for forecasting reservoir inflows and streamflows, and the distribution of software for the analysis of reservoir inflow and demand probabilities for optimization of reservoir operations has been done by software downloads and installations on local computers. It is challenging to keep this software current as computer operating systems and hardware evolve. Reservoir operators typically do not have time to update operations software.
