Learn More About Groundwater

What is Groundwater?

Groundwater fills the spaces between soil particles and fractured rock beneath the earth’s surface, acting as a large reservoir. On average, 40 % of all flow in United States rivers and streams originates as groundwater. Only 2.5 % of global water is freshwater – the rest is saltwater, in the Earth’s oceans and other places. Of all the freshwater available to people to use, 99% is groundwater.

Connecting to Groundwater

Enjoy fishing on National Forests and Grasslands? Lakes and streams generally depend on groundwater to keep water flows and temperatures consistent to support fish and other aquatic life. Many of our nation’s favorite swimming holes, hiking trails, and recreation spots are at springs, spring-fed rivers, and caves.

Communities and industries such as agriculture depend on water from wells in groundwater aquifers. Come visit your local National Forest or Grassland and learn more about how you can conserve and enjoy groundwater, or check out the links below.
