here is a link that you may want to save to your computer if you fish Allatoona and Carters Lakes. It will provide you the projected lake level out to 5 weeks or more.
http://water.sam.usace.army.mil/actmain.htm#5-weekThe solid Black line is the normal level. The solid blue line is where the lake is actually at (usually about a week behind the actual date) and the red dots are the forecast or planned level for five weeks. The other lines indicate the record highs and record low levels.
