GROUNDWATER USE    Water use figure

  • From 1979 to 2005, total water use in Calumet County has increased from about 5.0 million gallons per day to 7.7 million gallons per day in 2000 but decreased to 7.3 million gallons per day in 2005.*
  • The increase in total water use over this period is due primarily to an increase in commercial, irrigation and public use and losses.  An increase in domestic use also contributed to the overall increase.
  • The proportion of county water use supplied by groundwater has been consistently greater than 97% from 1979 to 2000 with a decrease to 73% in 2005.*
  • Water use in Wisconsin is generally estimated for the following categories:
    • Domestic
    • Livestock
    • Aquaculture
    • Irrigation
    • Industrial
    • Commercial
    • Public use and losses
    • Thermoelectric or mining

* Thermoelectric and mining data are not considered in water-use tables or figures on this web site. Thermoelectric-power water use is the amount of water used in the process of generating thermoelectric power. The predominant use of water is as non-contact cooling water to condense the steam created to turn the turbines and generate electricity.
