ExplanationBetween 1985 and 2015, water use per capita has decreased from 205 to 180 gallons per person per day.  During this same period of time, Thurston County's population has increased by more than 125,000 people.  Total water usage peaked in 2005 at 53.2 million gallons per day; in 2015, total water usage was 48.2 million gallons per day.

National Water Information System

The USGS investigates the occurrence, quantity, quality, distribution, and movement of surface and underground waters.  Water-use data is collected by area type (state, county, watershed or aquifer)   and source such as rivers or groundwater, and category such as public supply or irrigation. Water-use data has been reported every five years since 1950.  The USGS works in cooperation with local, State, and Federal agencies as well as academic and private organizations to collect and report total withdrawals. 


Sustainable Thurston Report Card

The Sustainable Thurston Report Card tracks how well the Thurston region is doing at maintaining our water supply.  The goal includes two targets for reducing per capita water use:

  • 15% below 2010 levels by 2020
  • 33% below 2010 levels by 2035
