GROUNDWATER USE    Water use figure

  • From 1979 to 2005, total water use in Marinette County has fluctuated from about 45.6 million gallons per day to 22.1 million gallons per day.*
  • The increase in total water use over this period to 1990 has been due to industrial and aquaculture use and decrease in total water use after 1990 is due to a decrease in industrial use.
  • The proportion of county water use supplied by groundwater has increased from about 8% to 48% during the period 1979 to 2000 and decreased to 35% 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.
