Losing and Gaining Streams

This data set depicts stream segments classified as either losing or gaining by the Missouri Department of Natural Resources' Missouri Geological Survey. Classification is dependent on flow loss through permeable geologic materials over a set distance at the time of the site visit. Stream classification is intended to depict sections of streams that 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 Regulations, 10 CSR 20-8. sos.mo.gov/adrules/csr/current/10csr/10c20-8.pdf.
