Delaware River Watershed Initiative Resources

The Delaware River Watershed Initiative (DRWI) is a cross-cutting collaboration that is working to conserve and restore the streams that supply drinking water to 15 million people in New York, New Jersey, Pennsylvania, and Delaware. In direct support of this initiative, Stroud Water Research Center is facilitating efforts to improve the capacity of watershed groups to conduct scientific investigations associated with DRWI projects, as well as to build general knowledge on the ecology of their watersheds and the broader basin.

These resources were created by the Stroud Center to assist DRWI efforts specifically focused on stream monitoring using EnviroDIY Monitoring Stations. They may also be of interest to community scientists and watershed groups working in other locations.

Tools for Engaging With Municipalities and the Public on Freshwater Issues

The Delaware River Basin Policy and Practice Workgroup has developed a number of documents to provide foundational science references for environmental advocates who are collecting stream data and who wish to communicate results to local government officials.

The following guidance documents are available on Manage My Watershed:

  • How to Engage With Municipal Leaders
  • Putting Stream Temperature Data to Work

Data and Data Visualization Resources

Volunteer Management Guidance Materials

Pennsylvania Organization for Watersheds and Rivers hosted an informative webinar by Suzanna Windon, Ph.D., assistant professor of youth and adult leadership at Penn State University: “Volunteer Motivations, Management, Recruitment, and Retention.” The ISOTURE volunteer model that Dr. Windon discussed seems like an excellent model for DRWI watershed groups to consider, in general and in relation to working with EnviroDIY monitoring stations.

WikiWatershed Toolkit

The WikiWatershed Toolkit is a suite of digital resources designed to help citizens, conservation practitioners, municipal decision-makers, researchers, educators, and students advance knowledge and stewardship of fresh water. The toolkit includes:

  • Model My Watershed®, a web app that lets you analyze geospatial data, model storms, and compare conservation or development scenarios in a watershed.
  • Monitor My Watershed®, a data portal for visualization of environmental sensor and macroinvertebrate monitoring data.
  • Runoff Simulation that shows how land use and soil together determine whether rainfall infiltrates into the soil, runs off into streams, or is evaporated and transpired by plants.
  • EnviroDIY™, a community of do-it-yourself enthusiasts sharing open-source ideas for environmental science and monitoring.
  • Leaf Pack Network®, an international network of teachers, students, and citizen monitors investigating their local stream ecosystems.
  • The Water Quality mobile app for recording water-monitoring data and enhancing learning activities for students and citizen scientists.
