GROUNDWATER USE    Water use figure

  • From 1979 to 2005, total water use in Crawford County has fluctuated from about 2.9 million gallons per day to about 3.8 million gallons per day.*
  • The fluctuations in total water use over this period is due to fluctuations in all usage categories except irrigation which increased.
  • The proportion of county water use supplied by groundwater has been 99% in 1979 and consistently about 98% from 1985 to 2000. 2005 decreased to 90%.*
  • 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.
