In the early 1900s, St. Croix Valley gained notoriety for its natural beauty. The arrival of railroads changed all that, though steamboats continued to be the most popular form of transportation. Steamboat day trips were the most popular form of tourist attraction in the region. Many boat owners realized early on that offering pleasure excursions would increase their profits. As a result, steamboats continued to be the most popular form of transportation and tourism in the region.
The Army Corps of Engineers wanted to rehabilitate lower St. Croix townships, and its natural beauty deserved national recognition. But it was difficult for them to get the land because of the dams and locks. After all, the Corps of Engineers was allowed to use relief funds to build the Red Wing Dam, and the river backed up on St. Croix for two years. The dam caused a slackwater pool in the river, and conservationists were appalled. Norelius, however, wanted to see the land turned into cottages and townships.
