Sediment data have been collected at 279 locations within the Mid-Arkansas and Upper-Red River basins in and along the borders of Oklahoma and Kansas. This compilation of sediment records presents tables and plots of all suspended-sediment data collected between 1930 and 1980. The publication not only provides a published source of all available suspended-sediment data, but more importantly provides potential users with an efficient means to access this large amount of data through the U.S. Geological Survey WATSTORE system.
