ISC races on Geist Reservoir on the northeast side of Indianapolis, IN. The reservoir sits on mainly flat farmland that has been heavily developed into lakeside housing. The northern and western shorelines are significant enough to influence wind direction while the southern and eastern shorelines are far more gradual and less influential. The racing area includes all of the reservoir to the south of the Fall Creek Rd. causeway (refer to the race course maps below). The island in the middle of the racing area is surrounded by shallow water and can have substantial influence on the local wind speed and direction in its proximity.

Online topographic maps of Geist Reservoir and the surrounding area are available at MapTech and TopoZone.
