Western Lake Superior <strong>Water</strong>shed<br />

<strong>Industrial</strong> <strong>Water</strong> <strong>Use</strong><br />

Industries in the Western Lake Superior watershed rely on the high quality surface<br />

water of Lake Superior and other surface sources <strong>for</strong> most of their needs. Only 0.15<br />

mgd of ground water was withdrawn from this watershed by industries, as indicated<br />

in Table 3.17a. The heavy water demands of the mining industry dwarf the other uses<br />

except <strong>for</strong> cooling water <strong>for</strong> steam power facilities, as shown in Figure 3.17a. Nearly<br />

300 mgd water was used by mining facilities in 2004 (Note: water used by the power<br />

industry specifically <strong>for</strong> mining activities is noted as a mining water use). As indicated in<br />

Figure 3.17b, 180 mgd of surface water was used <strong>for</strong> once through cooling water<br />

systems <strong>for</strong> steam power facilities. Pulp and paper processing, chemical processing,<br />

sand and gravel washing, and a concrete products industry were the other industry<br />

types residing in the Western Lake Superior watershed.
