Flood Data Collection in Pennsylvania - Rapid Deployment Network

USGS is helping identify potential locations in Pennsylvania where additional or updated water-level data may be needed during or after major storm events. Pre-identification of these locations supports expedited decision-making for site selection, resulting in safer and more timely installation of flood monitoring instruments.

Chester County (Pennsylvania) Monitoring Networks

Since 1969, the Pennsylvania Water Science Center has had a cooperative program with Chester County to measure and describe water resources. Cooperation has been primarily with the Chester County Water Resources Authority, with participation from the Chester County Health Department. The Chester County Monitoring Network web tool provides near real-time water data.
