This 2nd issue of Pennsylvania Waters highlights USGS data and mapping support for drought management, record flood peaks (in the same month!), recognition for Matthew Gyves, a Hydrologic Technician in the Pennsylvania Water Science Center, innovative streamflow monitoring methods, Potter County groundwater quality, new findings on lead and polonium in groundwater, and more.
A report on the groundwater quality of Potter County is the latest of seven publications characterizing water quality of aquifers underlying central and northern tier counties. Wells were sampled throughout Potter County with funding support from Commonwealth Financing Authority through the Marcellus Legacy Fund.
Hurricane Isaias swept over eastern Pennsylvania August 4th and 5th, dumping upwards of 8 inches of rain and resulting in wide-spread flooding. New high flow records included a measured streamflow of 6,920 cubic feet per second in the East Branch Brandywine Creek below Downingtown, Pennsylvania, the highest since the gage was installed almost 50 years ago.
Matthew C. Gyves, a Hydrologic Technician in the Pennsylvania Water Science Center's Downingtown Office, received the 2020 "Data Person of the Year" award from the USGS Water Resources Mission Area.
