Only 0.15 mgd of ground water was withdrawn from this watershed by industries, as indicated in Table 3.17a. The heavy water demands of the mining industry dwarf the other uses except for cooling water for steam power facilities, as shown in Figure 3.17a. Nearly 300 mgd water was used by mining facilities in 2004 (Note: water used by the power industry specifically for mining activities is noted as a mining water use). As indicated in Figure 3.17b, 180 mgd of surface water was used for once through cooling water systems for steam power facilities. Pulp and paper processing, chemical processing, sand and gravel washing, and a concrete products industry were the other industry types residing in the Western Lake Superior watershed.
