There were 29 dams built along the UpperMississippi  River by the U.S. Army Corps of Engineers.

The locks and dams were constructed by the U.S. Army Corps  of Engineers to provide a 9-foot channel for commercial navigation.

A key factor in a reservoir or a dam is the detritus on the bottom layer. The bottom feeders feed off of the detritus, this is where they get their energy source. Then there is the algae that zooplankton get their energy from, and then other organisms feed off of the zooplankton then giving off waste turning it into detritus, which enables the cycle to keep going. if we did not have algae in reservoirs, according to my food web, then it would make it very difficult for life to exist in a reservoir.

Threats To The Environment - Fisherman - Polution - No sun light!

There are not really any endangered species or threats in a dam other than fisherman catching the fish.

REFLECTION Dams and reservoir are very useful to humans. Dams are made in order to keep people safe from large depths of a lake or a river. The U.S. Army corps has created many dams along the Mississippi to keep the depth pools at 9 feet for navigation. Also in doing this they regulate how much water comes and goes through the dam, and this water that is being drained is used for things around the area such as irrigation, and water supply for people. All of this comes to use in the category of "non wasteful", because everyone can get good use out of dams and reservoirs, fisherman and just everyday people.
