Channel Stability Downstream From a Dam Assessed Using Aerial Photographs and Stream-Gage InformationK.E. JuracekAbstractThe stability of the Neosho River channel downstream from John Redmond Dam, in southeast Kansas, was investigated using multiple-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 six-mile river reaches and four stream gages were used in the analysis. Results indicated that, aside from some localized channel widening, the overall channel change has been minor with little post-dam change in bankfull channel width. The lack of a pronounced post-dam channel change may be attributed to a substantial reduction in the magnitude of the post-dam annual peak discharges in combination with the resistance to erosion of the bed and bank materials. Also, the channel may have been overwidened by a series of large floods that predated construction of the dam, including one with an estimated 500-year recurrence interval.

The USGS has collected hydrologic information in Kansas since 1895 with the first USGS Cooperative
Water Program funding agreement for 6 streamflow gages with the Kansas Water Board. USGS collects streamflow
and gage-height data; reservoir content; water-quality and water-quantity data; suspended-sediment data;
and groundwater levels. Hydrologic studies are conducted on national, regional, statewide, and local levels.
The USGS in Kansas works cooperatively with 31 Federal, State, and local agencies, such as the Kansas Water Office, the U.S.Army Corps of Engineers, and the City of Wichita
