Who's Monitoring Your Watershed? - MapProject Home
Description - The line between watersheds, called a divide, is the highest ground between two streams. Click on your county below for a detailed map that will help you identify the watershed in which you live. Notice how often towns are situated on the divides and how often roads run along these ridges.

The Hydrologic Unit Code system is a way to classify watersheds by size. This is a national system used to communicate the size and relationship of natural stream systems. Every hydrologic unit (a watershed or part of a watershed) is identified by a unique HUC, a number that has 2 to 12 digits. The bigger the HUC number, the smaller the watershed.

Stream Team Volunteer Water Quality Monitors adopt watersheds of all shapes and sizes. Sometimes they choose to monitor a stream in a small watershed near their home. Other times they choose the watershed of a larger river where they enjoy fishing and canoeing, such as the Meramec. Chances are that wherever you live in Missouri, there will be a Volunteer Water Quality Monitor near you.

Missouri Watersheds - MapProject Home
Description - A watershed or drainage basin is a region where surface water converges to a single point. It can also be thought of as the area drained by a river or stream. The Hydrologic Unit Code (HUC) system is a national method used to classify watersheds by size. Every watershed is identified by a unique HUC number. The largest watersheds have only two digits, and the smaller watersheds they contain begin with those same digits. For example, an eight-digit watershed numbered 10280101 is one of many watersheds contained by the four-digit watershed 1028. This interactive map depicts the 8-digit and 12-digit watersheds that intersect Missouri. As you zoom in more detail will appear in the map.
