Grafton stands at the convergence of three fluvial systems in the Red River Valley, where the North Branch Park River, Middle Branch Park River, and South Branch Park River combine to form the main stem of the Park River. This hydrological nexus defines the city's layout and historical development, with the Grafton Dam and Vigness Dam managing the flow of these prairie waterways. The town's grid is established east of the river forks, showing residential pockets like Westwood and the nearby Saint Johns Cemetery. Outside the city limits, the landscape transitions into the large-scale agricultural blocks typical of Walsh County, crisscrossed by a network of rural roads such as County Hwy-6 and 148th Ave NE, which reflect the precise section-line surveying of the region.
