How can inflow be negative? Answer here. ACF basin diagram (PDF)

With the exception of the values for the change in 12 AM and 6 AM levels, all lake
level values to the right of the decimal point are 100'ths of a foot.

Lake Allatoona data now available (full pool rule still needs work)

* 'Last' means the last date the item of interest was lower or higher than the value for today. Example: the current 6AM full pool level is 1070.00 on January 1st, 2007, and the lake level has been slowly lowering. If the last date the lake was at 1070.00 was exactly two years ago, January 1st, 2005 will be displayed. This display is not intuitive, so feel free to email jcwren@jcwren.com with any suggestions.
