“Pennsylvania received very little rain over the summer. We want residents to be aware of these dry conditions and be mindful of their water use,” said Department of Environmental Protection Secretary Jessica Shirley. “DEP makes drought declarations based on long-term trends. A severe thunderstorm or a rainy week may not lift the drought status for a particular area.”
A Drought Watch is typically declared for a county with three of the four factors in a “watch” status. Residents are encouraged, but not required, to voluntarily reduce their water use by five to ten percent.
Drought declarations are based on four factors – precipitation, stream flows, groundwater levels, and soil moisture.
The DEP Drought Coordinator monitors these indicators in close partnership with the U.S. Geological Survey, which maintains gauges in streams and wells in many locations across Pennsylvania.
DEP makes its drought declarations after assessing the departures from normal ranges for periods of 3-12 months.

Water Supplier Restrictions
DEP also factors in information it receives from public water suppliers. DEP will not implement mandatory water use restrictions outside of a Drought Emergency.
Individual public water systems may implement their own conservation measures. While not required, residents and businesses are encouraged to voluntarily conserve water by reducing nonessential water use.
