Sediment Monitoring in the Neosho and Cottonwood River Basins Active
The USGS Kansas Water Science Center, in cooperation with the Kansas Water Office, maintains a sediment monitoring network on the Neosho and Cottonwood Rivers both up- and downstream from John Redmond Reservoir. The purpose of this network is to assess the sediment loads and trapping efficiency of John Redmond Reservoir, and provide data to state agencies to determine the effect of streambank stabilization efforts in the Neosho and Cottonwood basins.
Over a decade of sediment monitoring using turbidity as a surrogate has given insights into reservoir sediment loading. By utilizing relationships between turbidity (an optical property of water) and suspended sediment concentration (SSC) samples, models are created to compute “continuous” SSC values. From these data, sediment loads and yields can then be easily computed over both short and long time scales, which allows further computations of reservoir sediment loading. With longer-term computed SSC data, trends in SSC can be assessed and potentially related to how well watershed Best Management Practices (BMP’s) and streambank stabilization efforts are working.

The streamflow regimen of the Neosho River downstream from John Redmond Dam in southeastern Kansas has changed significantly since the dam's completion in 1964. The controlled releases from the dam have decreased the magnitudes of peak discharges and increased the magnitudes of low discharges. The trends in river stage for selected discharges also have changed at two of the streamflow-gaging statiAuthorsS.E. StudleyTransit losses and traveltimes for reservoir releases during drought conditions along the Neosho River from Council Grove Lake to Iola, east-central Kansas
Knowledge of the transit losses and water-wave traveltimes in the Neosho River for varying reservoir-release volumes and durations is necessary for proper management of water supply. Two reaches were studied along the Neosho River in east-central Kansas. The upper reach is from Council Grove Lake to John Redmond Reservoir, a distance of 83.0 river miles. The lower reach is from John Redmond ReservAuthorsW. J. Carswell, R. J. HartTransit losses and traveltimes for water-supply releases from Marion Lake during drought conditions, Cottonwood River, east-central Kansas
A streamflow routing model was used to calculate the transit losses and traveltimes. Channel and aquifer characteristics, and the model control parameters, were estimated from available data and then verified to the extent possible by comparing model simulated streamflow to observed streamflow at streamflow gaging stations. Transit losses and traveltimes for varying reservoir release rates and durAuthorsP. R. Jordan, R. J. HartAvailability of natural and regulated streamflows for instream uses during historical droughts, lower Neosho River, southeastern Kansas
The effects of three historical droughts on streamflows available for instream use on the lower Neosho River at Iola and Parsons, Kansas, were investigated. Natural streamflows that occurred during the three droughts were compared to the multiple-use and water-quality streamflows recommended by State agencies. A reservoir model was used to investigate the effects of John Redmond Reservoir on the nAuthorsR. J. Hart, T. C. Stiles - Partners
