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.

Sediment concentrations and loads upstream from and through John Redmond Reservoir, east-central Kansas, 2010–19
Streambank erosion and reservoir sedimentation are primary concerns of resource managers in Kansas and throughout many regions of the United States and negatively affect flood control, water supply, and recreation. The Cottonwood and upper Neosho Rivers drain into John Redmond Reservoir, and since reservoir completion in 1964, there has been substantial conservation-pool sedimentation and storage
May through July 2015 storm event effects on suspended-sediment loads, sediment trapping efficiency, and storage capacity of John Redmond Reservoir
The Neosho River and its primary tributary, the Cottonwood River, are the main sources of inflow to John Redmond Reservoir in east-central Kansas. Storm events during May through July 2015 caused large inflows of water and sediment into the reservoir. The U.S. Geological Survey, in cooperation with the Kansas Water Office, and funded in part through the Kansas State Water Plan Fund, computed the s
Effects of May through July 2015 storm events on suspended sediment loads, sediment trapping efficiency, and storage capacity of John Redmond Reservoir, east-central Kansas
The Neosho River and its primary tributary, the Cottonwood River, are the main sources of inflow to John Redmond Reservoir in east-central Kansas. Storage loss in the reservoir resulting from sedimentation has been estimated to be 765 acre-feet per year for 1964–2014. The 1964–2014 sedimentation rate was almost 90 percent larger than the projected design sedimentation rate of 404 acre-feet per yea
Relations between continuous real-time turbidity data and discrete suspended-sediment concentration samples in the Neosho and Cottonwood Rivers, east-central Kansas, 2009-2012
The Neosho River and its primary tributary, the Cottonwood River, are the primary sources of inflow to the John Redmond Reservoir in east-central Kansas. Sedimentation rate in the John Redmond Reservoir was estimated as 743 acre-feet per year for 1964–2006. This estimated sedimentation rate is more than 80 percent larger than the projected design sedimentation rate of 404 acre-feet per year, and r
Assessing the potential of reservoir outflow management to reduce sedimentation using continuous turbidity monitoring and reservoir modelling
In-stream sensors are increasingly deployed as part of ambient water quality-monitoring networks. Temporally dense data from these networks can be used to better understand the transport of constituents through streams, lakes or reservoirs. Data from existing, continuously recording in-stream flow and water quality monitoring stations were coupled with the two-dimensional hydrodynamic CE-QUAL-W2 m
Sedimentation, sediment quality, and upstream channel stability, John Redmond Reservoir, east-central Kansas, 1964-2009
A combination of available bathymetric-survey information, bottom-sediment coring, and historical streamgage information was used to investigate sedimentation, sediment quality, and upstream channel stability for John Redmond Reservoir, east-central Kansas. Ongoing sedimentation is reducing the ability of the reservoir to serve several purposes including flood control, water supply, and recreation
Characterization of Suspended-Sediment Loading to and from John Redmond Reservoir, East-Central Kansas, 2007-2008
Storage capacity in John Redmond Reservoir is being lost to sedimentation more rapidly than in other federal impoundments in Kansas. The U.S. Geological Survey, in cooperation with the U.S. Army Corps of Engineers, initiated a study to characterize suspended-sediment loading to and from John Redmond Reservoir from February 21, 2007, through February 21, 2008. Turbidity sensors were installed at tw
Channel stability of the Neosho River downstream from John Redmond Dam, Kansas
The stability of the Neosho River channel downstream from John Redmond Dam, in southeast Kansas, was investigated using multi-date aerial photographs and stream-gage information. Bankfull channel width was used as the primary indicator variable to assess pre- and post-dam channel change. Five 6-mile river reaches and four stream gages were used in the analysis. Results indicated that the overall c
Geomorphic effects of overflow dams on the lower Neosho River, Kansas
The purpose of this report is to characterize the geomorphic (channel-changing) effects of overflow dams on the lower Neosho River channel in southeastern Kansas. Specifically, the report describes the types, upstream and downstream extents, and stability of the geomorphic effects in relation to site-specific, human-caused and natural conditions that may affect the channel’s response to the overfl

Changes in high-flow frequency and channel geometry of the Neosho River downstream from John Redmond Dam, southeastern Kansas
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 stati
