Two federal reservoirs in Kansas have been losing significant amounts of water storage capacity because of sedimentation, according to a study by the U.S. Geological Survey. The study also shows that the reservoirs can’t be expected to last indefinitely.
At least 95 percent of the sediment that flowed into Kanopolis Lake and Tuttle Creek reservoirs stayed in those reservoirs during two recent years, according to the study.
Water storage at Kanopolis, which is located outside Salina, dropped 34 percent. Tuttle Creek, located near Manhattan, saw storage drop 43 percent.
The reservoirs were built more than 50 years ago for water storage, flood control and recreation.
