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.

Air Quality Monitoring - MapProject Home
Description - Staff in the air quality monitoring section operate instruments at numerous locations around the state as part of a network to monitor air pollutants known to affect people's health. This interactive map shows the locations of those monitors. Use the identify tool to see what parameters are monitored at a site, or use the hyperlink tool to view data from that site.

Brownfields and Voluntary Cleanup Program Sites - MapProject Home
Description - The Brownfields/Voluntary Cleanup Program (BVCP) provides property buyers, sellers, developers, bankers, development agencies, local government and other voluntary parties with technical assistance and oversight for the investigation and remediation of contaminated properties, in return for a Certificate of Completion, to bring them back into productive use. Many of these properties are not eligible for regulatory oversight from other programs within the Department of Natural Resources. Thus, the BVCP is oftentimes the only means for these properties to receive a Certificate of Completion. Enrolled projects may be eligible for financial assistance in the form of state and federal tax credits to help offset the cost of cleanup. There are fifty BVCP sites known as "Hidden Treasures", which are a selection of BVCP success stories that were examined to measure the economic and environmental impact of cleanup. Sources of information on the Hidden Treasures project included: the Missouri Department of Economic Development, the Environmental Protection Agency, local government Web sites, online business journals, newspaper articles, property owners' Web sites, site visits and interviews with property developers.

Missouri's Current 303(d) Listed Waters - MapProject Home
Description - Section 303(d) of the federal Clean Water Act requires that each state identify waters that are not meeting water quality standards and for which adequate water pollution controls have not been required. Water quality standards protect such beneficial uses of water as whole body contact (such as swimming), maintaining fish and other aquatic life, and providing drinking water for people, livestock and wildlife. The 303(d) list helps state and federal agencies keep track of waters that are impaired but not addressed by normal water pollution control programs.

Missouri Water Quality Standards - Stream and Lake Classifications and Use Designations - MapProject Home
Description - This data set contains Missouri Water Quality Standards (WQS) stream and lake classifications and use designations described in the Missouri Code of State Regulations (CSR), 10 CSR 20-7.031 (Tables G and H).

Water Quality Assessment Viewer - MapProject Home
Description - This map project contains information from the Water Quality Assessment system.

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.
