New USGS Groundwater and Drought Web Pages

The U.S. Geological Survey (USGS) is pleased to announce the release of a new set of web pages highlighting, “Groundwater and Drought.”  The objective is to call attention to the role of groundwater in drought.  As described on the web pages, groundwater is important during all hydrologic droughts:


  • Groundwater may be an alternative or supplemental source of water during periods of drought.
  • Reduced groundwater levels due to drought or increased pumping during drought can result in decreased water levels and flows in lakes, streams, and other water bodies.
  • Changes in groundwater/surface-water exchange can result in changes in water quality.
  • Decreased groundwater flow to surface waters can affect aquatic ecosystems that rely on a continuous supply of groundwater to sustain aquatic habitats and stream flow.
  • Reduced heads in aquifers can result in land subsidence.


We encourage others to link this page to your own drought pages.  If you have any questions, please contact Cian Dawson at
