Pennsylvania Waters - Fall 2021 - Issue 5
This issue of our Pennsylvania Water Science Center Newsletter includes high water from Hurricanes Ida and Henri, removal of a low-head dam in York County, state of the art USGS monitoring and modeling of stream temperature in the Delaware River Basin, and more.

Spring Grove Weir Removal
Pennsylvania Water Science Center personnel remove broad-crested weir, Codorus Creek at Spring Grove
Hurricane Ida Water Footprint Data Visualization
As precipitation accumulated over DE, PA, NJ, NY, CT, RI, and MA, stream water levels increased above flood stage in several locations.
Geophysical and video logs of selected wells at and near the former Naval Air Warfare Center Warminster, Bucks County, Pennsylvania, 2017-19
The U.S. Geological Survey (USGS) collected borehole geophysical and video logs in 17 open-hole wells in Northampton, Warminster, and Warwick Townships, Bucks County, Pennsylvania during 2017–19 to support detailed groundwater investigations at and near the former Naval Air Warfare Center (NAWC) Warminster, where groundwater contamination with per- and polyfluoroalkyl substances (PFAS) had become
Science Outreach at Riverview High School
USGS staff participated in science outreach at Riverview High School, where students learned about environmental science and took part in interactive learning experiences.
Northeastern U.S. Streams During Tropical Storm Henri
Streamflow and water level changed dramatically as Tropical Storm Henri made landfall in the northeastern U.S. in late August, 2021, as shown by the Water Footprint Data Visualization.
Deciphering the U.S. urban stream pesticide signature
A new USGS study reports that 16 dissolved pesticides were consistently detected in small streams in 16 urban centers across five regions of the United States. These 16 pesticides can be considered as "urban signature pesticides" (USPs) that are common in small urban U.S. streams.
Methods for estimating regional skewness of annual peak flows in parts of eastern New York and Pennsylvania, based on data through water year 2013
Bulletin 17C (B17C) recommends fitting the log-Pearson Type III (LP−III) distribution to a series of annual peak flows at a streamgage by using the method of moments. The third moment, the skewness coefficient (or skew), is important because the magnitudes of annual exceedance probability (AEP) flows estimated by using the LP–III distribution are affected by the skew; interest is focused on the ri
Forecasting drought probabilities for streams in the northeastern United States
Maximum likelihood logistic regression (MLLR) models for the northeastern United States forecast drought probability estimates for water flowing in rivers and streams using methods previously identified and developed. Streamflow data from winter months are used to estimate chances of hydrological drought during summer months. Daily streamflow data collected from 1,143 streamgages from April 1, 187
Development of a screening tool to examine lake and reservoir susceptibility to eutrophication in selected watersheds of the eastern and southeastern United States
This report describes a new screening tool to examine lake and reservoir susceptibility to eutrophication in selected watersheds of the eastern and southeastern United States using estimated nutrient loading and flushing rates with measures of waterbody morphometry. To that end, the report documents the compiled data and methods (R-script) used to categorize waterbodies by Carlson’s Trophic State
