Most numerical models of ground-water flow incorporate lakes as constant head nodes. We developed a computer package for the widely used MODFLOW code to simulate three-dimensional steady-state and transient ground-water flow with fluctuating lake levels. This package considers precipitation to and evaporation from the lake surface, stream flow, and ground-water inflow and outflow for multiple lakes. We demonstrate the use of the package through the results of steady-state and transient simulations for a hypothetical ground-water flow problem involving a lake and two streams.
