| Background Information |
Sample Map
- Open to a single, known hydrogeologic unit
- Known well construction that allows good water-level measurements
- Located in unconfined aquifers or near-surface confined aquifers that
respond to climatic fluctuations
- Minimally affected by pumpage and likely to remain so
- Essentially unaffected by irrigation, canals, and other potential sources
of artificial recharge
- Long-term accessibility
- Well has never gone dry (not susceptible to going dry)
More than 200 of the network wells are equipped with telemetry that transmits
a reading of water level to an office by satellite or telephone. The data
typically are updated every 4 hours. Real-time hydrologic data are provisional
and have not been reviewed or edited. Each ground water record is considered
provisional until the data are published, which usually occurs within 6
months of the end of the water year (September 30).
The Ground Water Climate Response Network map layer shows the locations
of more than 300 wells in the United States and Puerto Rico. This map
layer was compiled by the USGS. Descriptive information includes the
station identification number, its location, and an indication of how
frequently data are collected from the well. Links are provided to
detailed information from each well. Additional information about USGS
water activities, including data from additional wells, is available
from the Water Resources
Program home page.
