The Charles, like any natural environment, is a complex, interconnected, living, changing system. At CRWA, our work is guided by the philosophy that we cannot address and manage problems in the Charles without understanding them. Collecting and analyzing our own data is a critical piece of this process and the backbone of CRWA’s advocacy and design work. Whether monitoring is conducted by staff, interns or volunteers, everyone follows strict monitoring protocols to ensure we collect the most accurate data available. In celebration of World Water Monitoring Day, read on to learn more about five ways CRWA monitors the Charles every day.
