The Oklahoma Conservation Commission monitors a selection of small streams statewide to qualify and quantify stream health statewide. This assessment helps identify potential impacts from nonpoint source pollution but also helps identify healthy streams. The map below highlights most of the streams currently monitored by our Blue Thumb volunteers and Rotating Basin Programs. Click on a square on the map for a summary of the information collected on that particular stream. Visit our monitoring page to learn more about how and why we do stream assessments, and the types of data we collect.
