Water Quality Division

Rotating Basin Monitoring Program

Oklahoma is committed to systematically identifying waters impaired by nonpoint source pollution. The Water Quality Division has developed a strategy to monitor small feeder streams on a rotational basis to determine the impacts of non-point source pollution on the water resources of the state. This rotational monitoring program, which rotates into two new basins every two years, supports the state's ambient monitoring program. Through the Rotating Basin Monitoring Program, chemical, physical, and biological sampling is done on 300 priority streams in five watershed basins across the state. Each year monitoring begins in one basin, where streams are monitored for two years. Using this rotation, all basins and 300 streams are monitored every five years, and then the rotation begins again. Monitoring is used to:

• Determine the beneficial use status of streams,
• Collect information on sources of pollution,
• Evaluate success of past and current restoration projects, and
• Gather data for planning and implementing future restoration projects.
