Each month, our team of committed citizen scientists — or Streamkeepers — gather valuable data throughout our watershed. These Streamkeepers are the eyes and ears of the creek, venturing out to take photos and fill out information forms. With 21 miles of streams in the upstream part of our watershed, this monitoring would be impossible without their commitment. Our diverse team of Streamkeepers care about the creek! We appreciate their contributions.


This citizen science effort is funded through the William Penn Foundation‘s Delaware River Watershed Initiative (DRWI). The goal of the DRWI is to protect and restore the Delaware River Basin’s water quality and overall ecological health. Participating organizations are implementing stream restoration and green infrastructure projects as well as informing municipal stormwater permits and public investments, using data gathered through aligned, science based efforts. The Academy of Natural Sciences and Stroud Water Research Center are leading the watershed analysis work, and guiding us as we train and mobilize these citizen scientists.
