Water levels changed by more than 5 feet in a two day period.  Winds from about 200 to 240 degrees SW drive water out of the lower bay.  This was the case on November 13, 2005 when water levels dropped below 574 feet.  Winds peaked at 56 mph from a direction of 220 degrees on November 13th.  Winds from the NE (30 to 60 degrees) funnel water into the lower bay as was the case on November 15th when water levels peaked at 579.5 feet.
