USGS groundwater and surface water monitoring data contributed to the August 31, 2022 drought watch declaration for 36 counties by the Pennsylvania Department of Environmental Protection (PaDEP). The last drought watch ended in February 2021.


Streamflow and groundwater levels, National Weather Service data on precipitation, and Climate Prediction Center calculations of the Palmer Drought Severity Index (for soil moisture dryness) are used as indicators that help determine drought status. Trends in the USGS-provided information can be explored via our Web Tool
