The Mississippi River defines the border between Grant County, Wisconsin, and Dubuque County, Iowa, creating a complex corridor of waterways and islands. This landscape is marked by the winding courses of the Grant River and McCartney Branch, which feed into the main channel near McCartney. Significant island formations like Hurricane Island, Rosebrook Island, and Mulligan Island are separated from the shore by Hurricane Chute and Snyder Slough, illustrating the dynamic nature of the river's path.
