Sustainability of Idaho’s Water Resources

Water is the foundation of Idaho’s economy and culture; the lives and livelihoods of Idahoans depend on a reliable supply of water. We have many rivers, lakes, reservoirs, groundwater aquifers, geothermal resources, and natural springs that support diverse economic and community interests including agriculture, aquaculture, industrial uses, public drinking water supplies, energy development, recreation, and more.

Sustainability is the active stewardship of Idaho’s water resources to satisfy current uses and assure future use of this renewable resource in accordance with State law and policy. Under guidance from the Governor, the IWRB is working to develop and implement actions that promote water sustainability.
