A Step by Step Guide to Measuring Stream Flow

Today we’ve got a special video for you about how to measure stream flow. This tutorial is one of the ways we try to share with you best practices for determining water quality and stream health with help from EPA.

Tools

Ball of heavy-duty string, four stakes, and a hammer to drive the stakes into the ground. The string will be stretched across the width of the stream perpendicular to shore at two locations. The stakes are to anchor the string on each bank to form a transect line.
Tape measure (at least 20 feet)
Waterproof yardstick or other implement to measure water depth
Twist ties (to mark off intervals on the string of the transect line)
An orange and a fishing net (to scoop the orange out of the stream)
Stopwatch (or watch with a second hand)
Calculator (optional)
