Permanent piling for submergible dike to be used for cofferdam construction at the Onalaska dam, under construction on the Upper Mississippi as part of Upper Mississippi River improvements. To drive piling for this cofferdam it was necessary that a crane be moved over the ice, or that the ice be cut and moved through the water on a barge. An unusual procedure was adopted. The snow was cleared back from the surface of the ice and piled up to form a cofferdam. This cofferdam was flooded artificially and the water permitted to freeze. By successively flooding and permitting the water to freeze, the ice was built up to a thickness sufficient to permit running the crane across the ice.
