[3] Logan Martin Lake is situated in the Northern Piedmont physiographic province of Alabama,[4] characterized by generally low ridges at the very southern reach of the Appalachian Mountains.

[5] Numerous aquatic species make their home in Logan Martin Lake with game and non-game fish being the dominant interest for human use.

Fish in Logan Martin lake are polluted with, in some cases, substantial amounts of Polychlorinated biphenyls (PCBs),[7] originating from Choccolocco Creek, and ultimately Anniston, Alabama.

The pollution culminated with several high-profile class action lawsuits in the early 2000s, one of which was led by attorney Johnnie Cochran [citation needed].

After steamships were replaced by roads and railroads, the site of proposed Lock 7[8] was selected for a large dam to provide hydropower, flood control, and recreation.

Its proximity to the large population center of Birmingham leads to heavy use by recreational boaters during the summer, and it is also used for skiing and swimming..
