Grand Rapids Flowage Access

The Grand Rapids Flowage boat ramp in Packard provides access to the Menominee River, a substantial waterway flowing through Marinette County. This large river (stream order 7) drains 3,957 square miles and maintains an average flow of 3,491 cubic feet per second, making it suitable for motorboats, canoes, and kayaks. The concrete ramp accommodates various vessel sizes and trailers.

Paddlers should be aware of the Menominee River's character: it's a powerful river with a 4.5 ft/mile average gradient and average velocity of 4.71 feet per second. The 116-mile length and 521-foot total elevation drop indicate significant current and potential rapids or fast water sections. The flowage itself offers calmer conditions for paddlers, but downstream exploration should account for the river's flow. Before launching, contact local authorities or check Wisconsin DNR resources for current conditions, dam locations, and any specific advisories for this section of the river.
