Example Question #1 : Hydroelectric Energy
All of the following are potential benefits to dams EXCEPT __________.
Water level management
Recreation opportunities from the resulting lake
Sedimentation buildup
Flood control
Clean electricity generation
Sedimentation buildup
Dams can be huge boons to local economies, and are a landmark of human engineering and achievement; however, they do carry serious consequences to the natural environment. They lead to sediment buildup, which hurts the flow of nutrients downstream, ruins the natural riverscape, and can cause the area behind the dam to become more shallow.
