Dams and Reservoirs
• Benefits:– Ensure year-round supply
of water with regulated flow
– Generate electricity– Provide recreational
activities• Disadvantages– Alter the ecosystem– Reduce sediment load

Dams and Reservoirs- Problems created by them
• Salmon Population in Columbia River very low due to dams that impede migration
• Fish ladders help, but are not effective enough

Dams and Reservoirs• Glen Canyon Dam
– Regulated flow has changed ecosystem• To rectify situation
– Canyon has been flooded several times– Small floods compared to natural floods– Still helps rebuild habitat
