For the month of October 2017 we see lake levels deviated quite significantly from the five year moving average. While it does not appear Ameren actively lowered lake levels in mid-October, I'm sure they took advantage of the lower than usual levels to advance maintenance work on Bagnell Dam. As for the remainder of the year, lake levels should remain around 658 until the drawdown next year. barring unusual weather or any measures taken by Ameren to do work.
