The warehouse was listed on the National Register of Historic Places in 1994 for having local significance in the themes of commerce and transportation. It was nominated for being a rare surviving reminder of a brief period when wheat was becoming the most important agricultural crop of the Upper Midwest yet steamboats were still the leading form of transportation.
