This data set depicts stream segments classified as either losing or gaining by the Missouri Department of Natural Resources (DNR), Missouri Geological Survey (MGS). Classification is dependent on the change in flow rate over a set distance at the time of the site visit. Stream classification is intended to depict sections of streams which are either losing water flow to the subsurface or gaining water flow from the subsurface. Stream classification is required for certain site evaluations under Missouri Code of State Regulation (CSR), 10 CSR 20-8.
This data was collected from the Missouri Spatial Data Information Service (MSDIS).
