Thurston County’s water supply comes from groundwater aquifers and surface water sources like lakes and rivers. For many years, water use increased along with the region’s population. As population continues to grow, using the water we have more efficiently will help ensure our region has adequate water to sustain both people — including residential, commercial, and agricultural activities — and stream flows that provide good habitat for fish and other wildlife, and support recreation and other uses.
Water use per capita decreased significantly between 2010 and 2015, the last dates for which data are available. With an increase in population, use of domestic and public supply water also increased. However, reductions in water use for industry, irrigation and aquaculture have offset this. Overall, water use has decreased since 2005, and the region is on schedule to meet its 2020 target.
