PADEP WQI Mapper
WQI Mapper README DEP’s Water Quality Index (WQI) uses concentrations of 21 physicochemical parameters to index an overall score from 1-100 (poor-good). The results are based on how similar a site’s water quality is to water quality dominated by one of four major land use/covers, referred to as Sub-WQI (SWQI) scores. The lowest SWQI of the fo...

Importing PASDA spatial data into R
In this tutorial, you will learn how to import Pennsylvania Spatial Data Access (PASDA) features into R. Step 1. Explore PASDA to identify the feature you’d like to import. In this case I want to import Pennsylvania Department of Environmental Protection (DEP) data, so I’ll search by provider from the PASDA homepage. Alternatively, you can se...

Hydrologic Condition Interpolation
Goals Streamflow estimation is essential for many monitoring and assessment activities. However, sampling sites are rarely colocated with USGS streamflow gages. There are many techniques, but this novel approach pairs streamflow magnitude (hydrologic condition) with the rate of change. This is an attempt to characterize 1) hydrologic condition, in...

Interstate Macro Acid Tolerance Comparisons
README PADEP has recently developed a wadeable freestone acidification assessment method. One biological metrics used for assessments of acidified surface waters is the Acid Tolerance Index (ATI), which relies on Acid Tolerance Values (ATVs) developed for 112 macroinvertebrate taxa. These ATVs represent organism acid tolerance on a 0 (sensitive to ...

Oemopteryx or Taenionema?
README Two Taeniopterygidae taxa: Taenionema and Oemopteryx are difficult to identify, especially when larvae are not late instars. We have consulted multiple taxonomic experts to gain insight on ID characteristics, ecology, and habitat preferences of these genera. Consult the Expert Input tab for additional information. The SLIMS database has 3 ...

2022 Bio Meeting RBP training
Physical Habitat Assessment Results README PADEP conducted a physical habitat assessment training/calibration during the 2022 Biologists Meeting in Williamsport on October 20, 2022. The results were compiled and examined to identify parameters with weak precision that may deserve attention during future training/calibration events. Another obje...
