Lake Fork receives more of it's rainfall from Oct-March than any other time of the year. That's why SRA draws down in the fall.
El Nino this year is one of the strongest, ever. Going to be in place through mid-2016. That means a very wet winter for the central and south central part of the country. The last two rain events were abnormal and due to El Nino and the jet stream shifting further south.
I'm sure SRA is planning for all of this in the draw down occurring now.
