Using Global Positioning System (GPS) technology, volunteers monitor the current conditions of their neighborhood creeks. In the summer and fall adventurous volunteers wade into local creeks, mapping the physical attributes of the stream channel (substrate, canopy cover, bank characteristics, etc.), extent and type of native and invasive vegetation, and human influences (outfalls, dams, etc.).

Joining a data collection event is a fun way to explore parts of your urban environment most people never see.  GPS Creek Surveys are more than just fun…they’re science!
