There are concerns that removal and trimming of vegetation during expansion of the Hayward Airport in Sawyer County, Wisconsin, could appreciably change the character of a nearby cold-water stream and its adjacent environs. In cooperation with the Wisconsin Department of Transportation, a two-dimensional, steady-state groundwater-flow model of the shallow groundwater-flow system near the Hayward Airport was refined from a regional model of the area. The parameter-estimation code PEST was used to obtain a best fit of the model to additional field data collected in February 2007 as part of this study. This report describes the refinement and recalibration of a two-dimensional, steady-state groundwater-flow model, which is described in detail in Juckem and Hunt (2007). Additional groundwater-level and streamflow data collected near the Hayward Airport formed the basis for refinement and recalibration of the regional model. The refined, recalibrated model of the shallow hydrologic system near the Hayward Airport was used as a tool to delineate the groundwater.contributing area of the Northern Tributary. The refinement and recalibration of the model is discussed, and the results of the contributing-area simulation are described.
