Schools/classrooms participating in Stream Leaders will complete an outdoor, stream monitoring day twice a year – once in the spring and once in the fall. Spring is help end of April through May and Fall is held throughout the month of October.
During stream monitoring day, students complete three different assessments of the stream and water quality.
Biological Assessment: students collect, sort and identify the Benthic Macroinvertebrates found in the stream. They learn how to determine water quality of the stream according to the pollution tolerance of the organisms they found in the stream.
Chemical Assessment: students conduct a series of chemical tests (pH, phosphates, nitrates, dissolved oxygen, temperature, turbidity, fecal coliform bacteria, biological oxygen demand). Using this data, the students then assess the chemical health of the stream.
Physical Assessment: students observe and measure the physical conditions of the stream (weather conditions, average stream width, depth, velocity, flow, substrate, habitat types, riparian vegetation, surrounding land use, etc.)
