An inventory of the sediment sample collection stations in the Mississippi River Basin pertinent to the mission of the Corps of Engineers was conducted; 433 stations were located. Data for the 433 stations are presented in tables. For stations on the Arkansas, Atchafalaya, Kansas, Mississippi, Missouri, Ohio, Old, and Red rivers, these data include the river mile, water resource region, Corps of Engineers (CE) District, Office of Water Data Coordination (OWDC) station number, agency station number, station name, geographic coordinates of the station location, type of water body on which the station is located, period of record of the station, frequency and types of data collected at the station, method used to collect sediment samples, and agency reporting to the OWDC regarding sediment collection activities at the station. For other streams in the basin on which stations are located, the data in the tables include the CE District, OWDC stations are located, the data in the tables include the CE District OWDC station number, station name, period of record, and agency reporting to the OWDC. In addition, narrative summaries were prepared for 74 key stations selected on the basis of location, period of record, and reliability of reported data. The summaries are presented in Appendix A, and include information on the station site location, the collection and laboratory analysis of sediment samples taken at the station, and the reduction and reporting of the resulting data.

This investigation was Phase III of a three-phase study of the sediment regime of the Mississippi River Basin. Phase I resulted in the publication of inventory of Sediment Sample Collection Stations in the Mississippi River Basin. The Phase II study identified a downward trend in Mississippi River suspended-sediment loads that apparently began around the middle of the 20th century. The current study deals with suspended-sediment sampling, analysis, and load-computation procedures used at key stations on major streams in the Mississippi River Basin and the possible influence of these procedures on the downward trend. Keywords: Suspended sediments; Flood control; Rivers/capacity quantity; Sediment transport; Sediments/sampling/analyzers.

An inventory study concerning available stream sedimentation and flow data for the GREAT II (Great River Environmental Action Team II) watershed was conducted for the Sediment and Erosion Work Group of GREAT II. The study area covered the Upper Mississippi River and its tributaries between Guttenberg, IA, and Saverton, MO. These data were utilized to obtain rough estimates of annual sediment yields at individual sediment sampling stations by simple correlating monthly averaged suspended-sediment discharges with monthly averaged stream discharges. Based on these estimates, major sediment source areas were identified, and recommendations regarding installation of new sediment sampling stations for further baseline data were made. A review of some existing methodologies in estimating sediment yields also was made, and a plan of study to determine quantities of sediment delivered by tributary sources into the Mississippi River was proposed.
