Knierim, K.J., Wagner, D.M., Roland, V.L., and Nottmeier, A.M., 2015, Ozark Plateaus seepage run dataset, southern Missouri and northern Arkansas, 1982-2006: U.S. Geological Survey data release, http://dx.doi.org/10.5066/F7W9577Q.

This dataset complied 24 years of U.S. Geological Survey (USGS) discharge measurement data from 15 studies covering southern Missouri and northern Arkansas in the Ozark Plateaus Physiographic Province (Ozarks). Previously these data were only available separately from the original USGS studies. The dataset can be used in surface-water and groundwater investigations assessing water quantity, quality, and availability in the Ozarks. The data set can be combined with the "Ozark Plateaus seepage flow-line dataset, southern Missouri and northern Arkansas, 1982-2006" to view point and line data of previously published USGS seepage-run studies.Seepage-run data were collected by measuring discharge at points along a stream, as well as at tributaries and springs contributing water to that stream. Any differences between the upstream and downstream discharge measurements (greater than the measurement error and taking discharge from tributaries/springs into account) were interpreted as gaining streams (if downstream discharge was greater than upstream discharge) or losing streams (if downstream discharge was less than upstream discharge).The discharge data were originally collected as part of USGS surface-water and groundwater studies to quantify the amount of water gained or lost by streams to aquifers; in some cases the data were collected as part of larger studies, such as groundwater modeling or stream water-quality monitoring. The Ozarks are one of the major karst provinces in the United States, and karst geology is characterized by fractures and solution-enlarged conduits in soluble bedrock that allow intimate interaction between surface water and groundwater resources. Therefore, quantifying the interaction between surface water and groundwater is important for a better understanding of water quality and quantity in karst landscapes. The point data of discharge measurements are intended to be used with the “Ozark Plateaus seepage flow-line dataset, southern Missouri and northern Arkansas, 1982-2006" because seepage-run studies include both point (that is, discharge measurements) and line (that is, stream flow lines between adjacent discharge points) data. Users are additionally encouraged to read the original reports (which are referenced in the “source” attribute field) to fully understand the data collection methods, results, and interpretations of individual seepage-run studies.
