The reading early Thursday was 1068.62, an increase of .14 of a foot since Wednesday. That's still about three feet below full pool, which is 1071.
The lake is still about a foot lower than it was October 1, when the level was 1069.42.
Rainfall this week totaled more than 2 inches in many places in the Chattahoochee and Chestatee river basins which feed Lanier. It was the first significant rainfall all month, breaking a string of 24 days during which on a trace of rain was recorded, if that much, in most places.
Usually it takes a day or two or more for the lake to get the full benefit of rainfall totals like the ones recorded this week because it takes a while for runoff from the headwaters of the two rivers to reach the impoundment.
