Channel-bed elevation changes were assessed downstream from 24 large Federal reservoirs in Kansas using information from U.S. Geological Survey streamflow-gaging stations. Changes in river/stream stage associated with mean annual discharge indicated that channel-bed lowering had occurred downstream from most of the reservoirs. The net decrease in channel-bed elevation ranged from less than 1 foot to slightly more than 9 feet. The magnitude of channel-bed lowering downstream from the reservoirs likely was related to the composition of the channel bed.
