Groundwater Climate Response Network Mapper

About this tool

The USGS Groundwater Climate Response Network (CRN) is a system of wells and springs selected to monitor the effects of droughts and other climate variability on groundwater systems nationwide. The primary purpose of the CRN is to monitor the effect of climate on groundwater levels in unconfined aquifers or near-surface confined aquifers that are minimally affected by pumping or other anthropogenic stresses. The climate variations of interest are those that affect groundwater systems on monthly and longer time scales; not barometric or tidal influences.
