Ameren announced in early February that the low level draw down would probably occur on February 19th. Looking at the chart above would seem to confirm they hit their target at just under 655', but I wouldn't count on the draw down being over just yet. As you can see the recent rains elevated the lake by nearly a foot and half and power generation (green spikes) has already begun bringing levels back down. Typically early March (see the orange 5 year average line) is when the lowest levels are reached and the spring rains haven't begun in earnest so it is possible they will draw the lake back down toward the 655' mark.
