SIEGEL'S NATATORIUM
SIEGEL'S NATATORIUM. Established in July 1910 by A. Siegel, the natatorium was a walled structure with no roof that floated near the mouth of the ICE HARBOR. It featured a chute which swimmers could use to slide quickly into the water and a diving board. Unique to the structure was a "basket bottom" that could be raised or lowered to adjust the depth of the water. Attendants were constantly on hand to make this change.
The 1913 Dubuque and Dubuque County Directory stated that this was located at the foot of 3rd.
