In the fall of 1998, Stillwater Area High School (SAHS) biology students first began studying Valley Creek. Originally, their work was part of a Department of Natural Resources (DNR) Citizen Monitoring project. DNR staff trained SAHS biology teachers who in turn began monitoring Valley Creek with their 10th grade students. Since then, trout stream research has remained a popular part of the curriculum.
The students conduct a Benthic Macro- Invertebrate Survey every spring and fall (benthic macro-invertebrates are invertebrates such as insects, worms, crustaceans etc. that are visible to the naked eye and live at the bottom of streams). Their study also includes taking a number of measurements on site including depth, velocity, flow, and temperature. The invertebrates are collected and brought back to school for identification. By analyzing the quantity of species present, conclusions can be made concerning the overall health of the stream. Their data shows that the Valley Creek’s water quality ranges between good, very good and excellent.
Stream monitoring partners have played an essential role in keeping the study going for more than a decade. Washington Conservation District coordinates the project and checks the student’s identification work. The Valley Creek Watershed District generously provides the necessary funding.
Students and teachers both have really enjoyed the work. This project has been an excellent way for everyone to learn about the ecology of a stream and to understand how scientists and government agencies work together. Students also learn that there can be a role for citizen scientists in protecting our natural resources.
