Drought declarations/cancellations are made at the State level (the Governor/DEP Secretary)
through guidance provided by the State Department of
Environmental Protection (DEP) using data, analyses, and forecasts from the National Weather Service (NWS), the Susquehanna River Basin Commission (SRBC), and the United States Geological Survey (USGS). It should also be noted that
local municipalities and water authorities can ask for voluntary water conservation by their
customers, and even impose mandatory restrictions, outside of Drought Declarations.
