Physical/Flow Monitoring Equipment and Forms

The majority of physical monitoring uses visual observations and requires only a data form and a pencil. If taking a measurement of stream flow, additional equipment is needed, including string or twine, a permanent marker, a wiffle ball, and a stopwatch that goes to hundredths of a second. Most cell phone stop watches will suffice.

In addition, flow measurements require a yard stick and an open-reel 100-foot measuring tape.

Flow Monitoring: How much water is moving through the stream affects water quality
