Welcome to the Hydrologic Engineering Center’s web page for our Reservoir System Simulation program, HEC-ResSim. As one of HEC’s “Next Generation” (NexGen) software packages, HEC-ResSim is designed to be used to model reservoir operations at one or more reservoirs whose operations are defined by a variety of operational goals and constraints.

The purpose of this site is to enhance the support services we provide to our customers. We’ve provided a number of resources here to help you download software, resolve problems, report bugs, and suggest improvements to our products.
