Dec 29th Flood Update - Slowly Dropping
It appears lake levels crested last night around 10pm and the lake is now dropping as Ameren continues to operate the flood gates around 40% open. The flow rate is also decreasing in tandem. This is a likely attempt to reduce the amount of current this much water is creating. Keeping the water moving, only not too fast, helps prevent excess debris from moving downstream all at once. At this rate however, it will be several days before we see normal lake levels. It is likely this event will delay the start of the normal winter lake drawdown.
At the current rate of decline, the lake will reach normal full pool level of 660' close to the stroke of midnight on New Year's Eve.
By contrast, the winter drawdown will lower the lake level 10 feet from where it is now.

Dec 28th Flood Upate - 4PM CST
As of 4pm the lake level continues to rise, now at 663.79. Discharge has increased to over 103,000 cfs. Subtracting 35,000 cfs for flow available through the turbines, means 68,000 cfs is passing through the flood gates. The 12 flood gates are each capable of releasing 13,503 cfs for a total of 162,036 cfs.
By these numbers we can estimate that all 12 flood gates are open approximately 42%.

December Flooding Surpasses July's
December 28th. As of the 2pm CST reading, discharge is being held at about 102,500 cubic feet per second but lake levels are still rising, although slowing down. Currently the lake is at 663.73. If discharge remains above 100,000 it is possible the lake will not reach 664.
The maximum flow discharge during the summer flooding peaked at just over 85,000 cubic feet per second with a lake level high of 662.55.
Here's what's happening on the Osage River, below the dam. Up nearly 16 feet in 48 hours.

November 2015 Lake Levels and Discharge
No power generation to speak of in the first half of November meant lake levels stayed virtually constant. Rain and cold moved in and the lake reached full pool, nearly two and a half feet above the 5 year average. Power generation is clearly seen in the latter part of the month as average generating discharge dropped the lake towards more average levels.
