Today, two-thirds of Kansans rely on reservoirs for drinking water. However, there are challenges with maintaining them. They require protection from sedimentation, which uses up water supply storage space, and in the case of those here in Kansas, were only given about 50 to 100 years to last when built.
Kansas lakes, which were man-made reservoirs formed by building dams on rivers and streams, differ from those found in states like Minnesota which have a large number of naturally formed lakes. These man-made lakes become impacted by soil that washes away from land and riverbanks as sediment is carried downstream. As the water settles, the carried dirt drifts and settles in the bottom of these reservoirs. Over time silt stacks up, displacing water. The oldest reservoir, Kanopolis Lake, has passed its middle age and is filling up with loose dirt and silt. Many others, such as Tuttle Creek Lake and John Redmond Reservoir, have followed that same sedimentation trend.
