What is River Watch? River Watch is a program where high school students and their teachers monitor water quality of a river in their area. Each school involved is given a YSI Sonde, a turbidimeter, a Secchi tube, safety vests, and a sampling bottle to use as well as the necessary calibration solutions. Each group uses these tools to monitor dissolved oxygen, temperature, conductivity, pH, and turbidity of the river. Twice each school year, once in the fall and once in the spring, all of the schools are brought together for a workshop where they report on their findings and are provided information on some topic pertaining to water and water quality.
