==Hydrology==
Logan Martin Lake begins at the discharge of H. Neely Henry Dam near Ohatchee, Alabama (near the site of former Coosa River Lock 3)〔http://alabamamaps.ua.edu/historicalmaps/alrivers/index.html Map of Lower Coosa River, Ala., from Gadsden to Wetumpka; 1910; from collection of University of Alabama Historical Map Archive〕 and extends south to Logan Martin Dam near Vincent, Alabama.〔http://www.southerncompany.com/learningpower/tours_alabama.asp#Anchor-Logan-52079 Alabama Power Company, Energetic Tours in Alabama〕 The Coosa River is the primary inflow for the lake, in addition to numerous lakes and rivers. Prevailing flow is from the north to the south along a meandering course. The Coosa River arises in the Appalachian Mountains and its waters, and those of Logan Martin Lake, eventually discharge into Mobile Bay and the Gulf of Mexico through the Alabama River and Mobile River. The Lake is largely a run-of-the-river reservoir through its upper reaches. From the location of Lock 4 to the I-20 bridge, the river expands, but is still largely confined to the original course of the Coosa River and the immediate mouths of tributary streams rather than spreading over the floodplain like a typical reservoir. From the I-20 bridge in the Riverside area to the Logan Martin Dam (approximately 23 miles), the lake expands to a width much greater than the original river channel, with large areas of open water and many medium to large sized sloughs and creeks. The maximum depth at the dam is .〔(Facts about Logan Martin Dam )〕
