This case study is about whether or not the Lower Snake River Dams in Eastern Washington should be destroyed.  The reasons for destroying the dams are they are killing fish such as salmon which is a good source of food for townspeople and the Walla Walla and Umatilla Indians.  The reasons for keeping the dams pare because towns get irrigation with the help of dams, they help wheat barge businesses, and they are needed for electrical plants, boat ramps, and Army Corps.  It is up to Congress to decide if the dams should be destroyed or not.
